Abstract
Quantum dots (QD’s), are a class of semiconducting nanocrystals that can serve as photo emitters in screens or absorbers in solar cells. Nanocrystals can be made using a single-source precursor (SSP), which is created by taking multiple elements needed for the target, and combining them to create one single compound. This is an alternative to using a combination of precursors in a multisource approach. Nanocrystals in current consumer products are made from cadmium selenide, which is toxic to the environment. The Holland Lab at Idaho State University is researching different ways to synthesize quantum dots from materials that are more abundant and less toxic to the environment. This work emphasizes new synthetic routes to nanocrystals made from non-toxic materials such as copper, tin, zinc, gallium, or indium. Synthetic pathways for making CuGaS2 and Cu2ZnSnS2 using ethanedithiol complexes will be discussed.
