Title: Metal chalcogenide synthesis method and applications

Abstract

A method for synthesizing a metal chalcogenide nanocrystal (NC) material includes reacting a metal material and an ammonium chalcogenide material in an organic solvent material. The method provides that the metal chalcogenide nanocrystal material may be synthesized by a heating-up method at large scale (i.e., greater than 30 grams). Ammonium chalcogenide salts exhibit high reactivity and metal chalcogenide nanocrystals can be synthesized at low temperatures (i.e., less than 200° C.) with high conversion yields (i.e., greater than 90 percent).
