Sulfur precursors for nanostructured materials

Summary

Nanostructured materials have intriguing photoluminescent properties due to their small size. These properties are tunable based on the exact size of particle used, making nanocrystals excellent candidates for LED displays, bioimaging tools, and solar cells. However, current synthetic methods to make these nanocrystals are lacking in precision; it is difficult to produce a uniform sample with crystals of low dispersity. This technology uses a sulfur-containing thiourea precursor to make cadmium sulfide and lead sulfide nanocrystals in a highly controlled manner. The use of this precursor has the potential to generate nanocrystals of a consistent size for more precise optoelectrical devices.
