Abstract

On recent years, there have been increasing interests in preparation of unique quantum dots (QD's) with high quantum yields due to their potential utilities in applications, such as light emitting diodes (LED's), solar cells, and biological imaging. Using various methods we have incorporated different transitional metals into our Chalcopyrite crystal structure. This was done to study the changes in the band gap, quantum yield, and other properties of our earlier synthesized QD's. we have developed successful synthetic methods for preparing CuInZnS3 and AgInZnS3, with additional methods to potentially prepare Cu2ZnSnS4. the use of these elements in QD's can lower the cost and environmental hazards compared to those used in industry today. these Qd's have shown quantum yields of up to 30% and have been characterized by UV-Vis, XRD, TEM, ICP-OES, and Fluorescence.
