FIELD EMISSION SCANNING ELECTRON MICROSCOPE (FESEM)

The center for nanotechnology is equipped with a state of the art of scanning electron microscope for the analysis of microscopic materials. Scanning electron microscopes are a type of microscopes that bounces electrons (secondary) off of the surface of sample materials to generate images. Like other electron microscopes, scanning electron microscopes produce images with very high resolution due to the fact that electrons have very short wavelength.

The field emission scanning electron microscope (JSM-7100FT) at center is manufactured by JEOL USA, Inc. The JSM-7100FT is a highly versatile, easy-to-use analytical field emission SEM that offers a new level of expanded performance. This high resolution SEM is ideal for both imaging and analysis of nanostructures, and determining chemical composition of the sample through X-ray spectroscopy. By combining large beam currents with a small probe size at ANY accelerating voltage, the JEOL JSM-7100FT dramatically increases analytical resolution to the sub 100nm scale.

The FESEM has a resolution of 12 nm at 30kv and 3 nm at 15 kv. The magnifying power of the electron microscope ranges from 10 times to a million times. Schottky thermal field emitter is the electron microscope source. The FESEM is also equipped with a JED-2300 Energy dispersive microanalysis system that is used for elemental analysis.

ATOMIC FORCE MICROSCOPE (AFM)

The surface morphological characteristics of the nanomaterials are experimentally evaluated at the center for nanotechnology using Atomic Force Microscopy (AFM) manufactured by NT-MDT (Model: Solver next, NT-MDT). AFM atomic force microscopy (contact and non-contact mode). Sample size of 20mm diameter, 10 mm height. Scan range of 100x100x10µm with closed loop capacitance sensors. All possesses built-in optical microscope, motorized xy-positioning (5x5 mm, step size 0.3µm), and available field coverage of 3.4 mm-0.53 mm and resolution of 2 µm.

The NanoLog® Spectrofluorometer detects fluorescence in the near-IR from 800 to 1700 nm (optional multi-channel detection to 2 µm, single-channel detection to 3 µm), with visible and UV options possible. With the NanoLog® there is a specially designed software ideal for classifying SWNTs, performing energy transfer calculations, saving custom routines, and instrument layouts. A complete spectrum can be scanned as fast as a few milliseconds, and a full excitation-emission matrix scan can be taken in as little as seconds.

DELTAFLEX MODULAR FLUORESCENCE LIFETIME SYSTEM

The Center for Nanotechnology is equipped with a Delflex modular fluorescence lifetime system manufactured by HORIBA Scientific. It is easy to use and is highly sensitive. It is a compact, modular, time-correlated single photon counting (TCSPC) based lifetime system. It is capable of measuring luminescence lifetimes from 25ps to 1sec, depending on the choice of light source and offers picoseconds time resolution over a wavelength range from the UV to the near infrared (NIR). The modular nature of the design means it can be easily extended and upgraded using the comprehensive range of products. Delflex modular fluorescence lifetime system is composed of an optical system, light source, detector, single-photon counting module, data station and decay analysis software. 

SOLAR SIMULATOR

The cell performance was measured using 150 W fully reflective solar simulator with a standard illumination of air-mass 1.5 global (AM 1.5 G) having an irridance of 100 mW/cm2 (Sciencetech Inc.), London, Ontario, Canada. Reference 600 Potentiostat/Galvanostat/ZRA from GAMRY Instruments (Warminster, PA). 

DYNAMIC LIGHT SCATTERING

Nanomaterials have also been characterized at the center using a dynamic light scattering instrument from Horiba. The LB-550 measures particle size from 1nm to 6µm and a concentration range from ppm up to 40% solids, all in as little as 30 seconds, making it ideally suited to a wide range of applications. The LB-550 instrument can measure samples without dilution. With a standard analysis time of one to two minutes, the LB-550 is the fastest and most flexible particle size analyzer for the nanometer range of sizes. The Fourier-Transform/Iterative Deconvolution technique provides accurate results not only for average particle size, but also for distribution shape and identification of multiple modes, all without operator selections, a feature not found in most Photon Correlation Spectroscopy (PCS) instruments. Elimination of the need to select from alternative models and evaluating fitting errors provides confidence in the results and faster data analysis.

The instrument is equipped with a temperature-controlled cell holder and has a range of 5-70 degrees C for samples where size may change with temperature. Standard removable glass or disposable plastic cuvettes are used to eliminate sample cross-contamination, ease cleaning, and improve usability. Cells are available for sample volumes from 0.1-15ml. For high concentration samples where viscosity may affect results, a built-in viscometer option is available to provide accurate measurements at the time of analysis.

THERMOGRAVIMETRIC ANALYSIS (TGA)

Thermogravimetric analysis at the center is performed on a Thermogravimetric Analyzer (Discovery TGA, TA Instruments-Waters LLC, New Castle, DE ) and a conventional oven at 700 ◦C. Thermogravimetric analysis (TGA) also referred sometimes as thermal gravimetric analysis is used to analyze samples based on the ability of the sample complex to withstand higher temperatures. Typically the sample is heated and the mass is measured over time with change of temperature.

The Center for Nanotechnology in the Natural Science Department at Coppin State University is involved in innovation work on a number of fronts including dye sensitized solar cell studies, Gold nanaparticle work, and Terahertz Spectroscopy.

Dye Sensitized Solar Cell Research

Firstly, the center is actively engaged in cutting-edge dye sensitized solar cell research. Dye sensitized solar cells are third generation solar cells that are fabricated from simple materials and are generally less expensive and environmentally friendly. In this research effort, different organic and synthetic dyes are being used to harness solar energy for the production of electricity. The nanotechnology center is equipped with the state-of-the-art instrumentation such as solar simulator, potentiostat, and a spin coater which are very critical to the advancement of this particular type of research.

Different projects involving different components of dye sensitized solar cells have been carried out to improve the efficiency of solar cells. The following are examples:

Fabrication, Optimization and Characterization of Natural Dye Sensitized Solar Cell

The dyes extracted from pomegranate and berry fruits were successfully used in the fabrication of natural dye sensitized solar cells (NDSSC). The morphology, porosity, surface roughness, thickness, absorption and emission characteristics of the pomegranate dye sensitized photo-anode were studied using various analytical techniques including FESEM, EDS, TEM, AFM, FTIR, Raman, Fluorescence and Absorption Spectroscopy. Pomegranate dye extract has been shown to contain anthocyanin which is an excellent light harvesting pigment needed for the generation of charge carriers for the production of electricity. The solar cell’s photovoltic performance in terms of efficiency, voltage, and current was tested with a standard illumination of air-mass 1.5 global (AM 1.5 G) having an irradiance of 100 mW/cm2. After optimization of the photo-anode and counter electrode, a photoelectric conversion efficiency (η) of 2%, an open-circuit voltage (Voc) of 0.39 mV, and a short-circuit current density (Isc) of 12.2 mA/cm2were obtained. Impedance determination showed a relatively low charge-transfer resistance (17.44 Ω) and a long lifetime, signifying a reduction in recombination losses. The relatively enhanced efficiency is attributable in part to the use of a highly concentrated pomegranate dye, graphite counter electrode and TiCl4 treatment of the photo-anode.

Photophysical properties of near-IR cyanine dyes and their application as photosensitizers in dye sensitized solar cells

The performance of the cyanine dye-sensitized solar cells conformed to the photophysical properties of the cyanine dyes.

Photophysical, Electrochemical and Photovoltaic Properties of Porphyrin-Based Dye Sensitized Solar Cell

ABSTRACT

 Porphyrins occur in a number of important biomolecules and are also synthetically made for use as probe component of chemical and biological sensors. The performance of dye sensitized solar cells with two different porphyrin dyes was investigated in this work. The two porphyrin complexes comprised of a metal-free 5, 10, 15, 20-meso-tetrakis-(9H-2-fluorene-yl) porphyrin (H2TFP) and its Zinc complex (ZnTFP). UV-Vis, Fluorescence, and Fourier transformed infrared measurements of the two dyes were carried out to evaluate their absorption, emission and binding characteristics. Both dyes absorbed light in the UV-visible region all the way to the near-infrared. The surface morphology and elemental analysis of the porphyrin dye sensitized photoanodes were determined using Field Emission Scanning Electron Microscopy Imaging and Transmission Electron Microscopy Imaging. Cyclic voltammetry studies, current-voltage characteristics and the electrochemical impedance spectroscopic studies were also carried out. Solar-to-electric energy efficiency of H2TFP dye sensitized solar cell was higher (0.11%) than that of the zinc complex (0.08%). Thus the metal free porphyrin generated more power than the zinc complex under similar conditions. The impedance measurement also displayed less overall resistance for the free porphyrin (50 Ω) compared with the zinc complex (130 Ω). The LUMO levels of H2TFP and ZnTFP sensitizers were −0.87 eV and −0.77 eV respectively. Both of these LUMO values are higher than the lower bound level of the conduction band of TiO2 (−4.0 eV), ensuring the efficient injection of an electron from the excited porphyrin dye to the conduction band of the titanium dioxide.

Synthesis and Characterization of Free and Copper (II) Complex of N,N′-Bis(Salicylidene)Ethylenediamine for Application in Dye Sensitized Solar Cells

ABSTRACT

Dye sensitized solar cell represents a promising method for the conversion of solar energy to electric energy. In the present work free N,N'-bis(salicyli-dene)ethylenediamine and its copper (II) complex were synthesized, characterized, and investigated for use as dye sensitizers in the fabrication of dye sensitized solar cells. The dyes were characterized using UV-Vis, Steady State Florescence, and Fluorescence Lifetime, Thermogravimetric Analysis, Differential Scanning Calorimetry, and Cyclic Voltammetry. The thermogravimetric analyses of the ligand and the ligand Copper complex demonstrate the stabilizing effect of the copper ion on the ligand complex. Additionally, the copper ion is shown to stabilize the structure, as evidenced by the 150oC increase in the extrapolated onset temperature of the decomposition event. The ligand copper complex is further stabilized by the presence of the copper, which is determined by the 6.34% residue that remained at the end of the thermogravimetric analysis, compared with 0% residue when applying the same condition for the ligand without copper. The current-voltage characteristics of the cells and the electrochemical impedance were determined. The photovoltaic performance of the solar cell devices fabricated using N,N'-bis(salicylidene) ethylenediamine dye was found to be slightly better than those produced from the copper complex. The solar to electric power efficiency of the ligand-based dye sensitized solar cell was 0.14% and that of the copper complex was found to 0.12%. Although the difference in the cell efficiency is quite small, it is obvious that the insertion of Copper into the ligand did not enhance the performance of the solar cells. The photocurrent-photovoltage results are consistent with the absorption spectra that showed a more prominent band for the ligand. The free hydroxyl groups, present in the ligand but absent from the copper complex owing to their coordination with the copper metal, could be responsible for the difference in the performance of the devices. The hydroxyl groups get attached to the TiO2 and facilitate the transfer of electrons.

Comparison of the Performance of Dye Sensitized Solar Cells F abricated with Ruthenium Based Dye Sensitizers: Di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2’-bipyridyl-4,4’-dicarboxylato)Ruthenium(II) (N719) and Tris(bipyridine)Ruthenium(II) Chloride(Rubpy)

The photovoltaic performance of two ruthenium based dyes was measured and compared to assess the effect of anchoring groups on the current-voltage characteristics of dye sensitized solar cells. One of the two dyes, Di-tetrabutylammonium cis-bis(isothiocyanato)bis(2,2’-bipyridyl-4,4’-dicarboxylato)ruthenium(II), (N719) had an anchoring group - and the other, Tris(bipyridine)ruthenium(II) chloride (Rubpy), without an anchoring group. N719 showed a higher efficiency compared to Rubpy. The results were validated by density functional calculation.

Terahertz Research

Terahertz radiation, also known as “terahertz gap” is the frequency band (~0.1 THz to ~ 10 THz) sandwiched between the far infrared and microwave region of the electromagnetic spectrum. Terahertz radiation stimulates various resonances when they interact with different types of materials producing signals characteristic of the specific interaction between the radiation and the material. Until recently, terahertz technology received very little attention due to the difficulty in accessing, manipulating and detecting the radiation. New advances in technology, over the past couple of decades, have opened the door for an efficient and cost effective means of generating and detecting terahertz radiation. Terahertz spectroscopy is complementary to techniques such as Raman and infrared spectroscopy. The radiation is invisible, low energy, non-ionizing, noninvasive, and comparatively transparent to many materials with few exceptions such metals and liquid water. These properties make it safe and suitable for use in a myriad of application including the analysis of biological structures in their native state. Current applications of Terahertz include Spectroscopic analysis, imaging, material characterization, pharmaceutical product analysis, detection of concealed weapons, detection of diseases, and general inspection of products.

Terahertz Technology Research in Dye Sensitized Solar Cells (DSSC)

Another leading-edge research effort involves the use of terahertz radiation for the characterization of a variety of materials, chief among them being semiconductor devices. Terahertz radiation is in a region of the electromagnetic spectrum between infrared and microwave. Until recently, research involving terahertz radiation has been minimal due to the lack of sources for the generation and detection of the radiation. Recent discovery of sources for terahertz generation and detection has spurred innovative work in this area of research. Terahertz has the potential for biological analysis and also for security screening at airports and other restricted locations because they are able to generate images while being non-ionizing and less hazardous compared to X-rays.  We have used Terahertz radiation to characterize semiconductor materials and the photoanode component of dye sensitized solar cells.

Terahertz Technology Research with gold nanoparticles Research

In this work, we are investigating the use of a Terahertz multispectral reconstructive imaging technique to measure the size of individual gold nanoparticles and accordingly the number of unit cells in a given gold nanoparticle. Terahertz multispectral reconstructive imaging technique was used to measure the diameter of individual gold nanoparticles and by extension the number of unit cells and gold atoms in a given gold nanoparticle. The size as determined by Terahertz imaging was comparable, within limit of experimental error, to the size determined via Transmission electron microscopy. Terahertz radiation is non-ionizing and terahertz imaging instrumentation less expensive compared withelectron microscopes.

Synthesis and Characterization of Reduced Graphene Oxide and their Application in Dye Sensitized Solar Cells

Reduced graphene oxide has certain unique qualities that make them versatile for a myriad of applications. Unlike graphene oxide, reduced graphene oxide, is a conductive material and well suited for use in electrically conductive materials such as solar cell devices. In this study we report on the synthesis of graphene oxide as well as the fabrication and characterization of dye sensitized solar cell with a photoanode which is an amalgam of reduced graphene oxide and titanium dioxide. The synthesized reduced graphene oxide and the corresponding photoanode were fully characterized using ultraviolet-visible, Fourier transform infrared (FTIR) and Raman Spectrometry. The morphology of the sample was assessed using Atomic Force Microscopy, Field Emission Scanning Electron Microscopy, and Transmission Electron Microscopy and Energy dispersive X-ray spectroscopy. The photovoltaic characteristics were determined by photocurrent and photovoltage measurement of the solar cell. The electrical impedance of both sets of devices were also evaluated. Overall, the solar to electric power efficiency of the device with reduced graphene oxide was higher (2.02%) than the sample without the reduced graphene oxide (1.61%).

These gold nanoparticles are also being conjugated to MRI contrast agents such as gadolinium chelates and fluorophores such as indocyanine green for MRI and fluorescence imaging, respectively. Brand-new instrumentation such as Transmission Electron Microscope, Scanning Electron Microscope, Atomic Force Microscope, Absorption and Emission Spectrophotometers have facilitated the work at the center.

Terahertz spectroscopic studies of quantum dots-conjugated gold nanoparticles

Composite structures of metal nanoparticles and semiconductor nanomaterials present unique properties that have made them candidates for various applications. The properties of these hybrid structures to a large extent depend on the design and specific material used in to produce them. Here, we present work on the synthesis and characterization of CdSeS/ZnS quantum-dot–gold nanoparticles hybrids (denoted as QD-GNP) and studies on their interaction with terahertz radiation. The prepared QD-GNPs were characterized using UV-vis spectroscopy (UV-vis), Dynamic Light Scattering (DLS), Transmission Electron Microscopy (TEM), Fluorescence Spectrometry and Photoluminescence Lifetime measurement.  The wavelength of maximum absorption of the gold nanoparticles was 520 nm while that of the quantum dot was 609 nm. The peak absorption band of the hybrid solution was around 520 nm. Transmission electron microscopy imaging revealed the surface morphological features of the quantum dot and gold nanoparticle. Strong photoluminescence quenching was observed upon the conjugation of the quantum dots with gold nanoparticles. The observed difference in the lifetime of free quantum dot and the hybrid QD-GNP was an indication of the bonding between the quantum dot and gold nanoparticles. A biexponential decay was observed with a lifetime of 3.57 ns for bare quantum dots and 1.05 ns for QD-GNP as for the faster component and the slower component 15.09 ns and 8.30 ns QD AND QD-GNP, respectively. Unique features were observed on the terahertz spectra of the composite structures in comparison with that of the either the QD or the GNP

Preparing the Next Generation of Educators

The Department of Teaching and Learning continues our historic legacy of preparing future teachers to make a difference in the lives of students in Baltimore and beyond. When Coppin was founded in 1900, it had one program designed to prepare African-American elementary school teachers.

In 1950, when Coppin joined the Maryland higher education system (now called University System of Maryland, USM) we became Coppin Teachers College. Still later, our name changed again, this time to Coppin State Teachers College. Teaching is in the fabric of who we are as a University and a department; it colors everything we do and our dedication to our students.

We set rigorous standards for our undergraduate and graduate programs in early childhood education, elementary education, and special education, which are reflected in each program’s accreditation by the Council for the Accreditation of Educator Preparation (CAEP), and approval from the Maryland State Department of Education (MSDE).

We stay committed to graduating teacher candidates who seek to be positive change agents in the lives of the students they serve. To align with MSDE’s redesign of Teacher Education, we equip our students to be data-driven decision makers and competent professionals with strong:

• Academic background,

• Hands-on professional experience and

• Pedagogical and theoretical knowledge.
