Covalent metal phosphide nanocrystals represent an important class of materials in a diverse set of applications, including catalysis, solid-state lighting and solar energy capture. Our ability to harness the unique properties of these quantum confined semiconductors relies on our ability to prepare monodisperse samples in high yield and with near unity quantum efficiency. Addressing these challenges will require controlling the solution synthesis of these nanocrystals with atom-level precision. This is particularly challenging for phosphide semiconductors due both to the nature of the reagents used to make the particles and to the covalency of the particles themselves. This work will outline the progress we have made on understanding the precursor conversion reactions, nucleation and growth mechanisms of indium phosphide and zinc phosphide quantum dots.
