Abstract
A method of synthesizing metal chalcogenide nanocrystals involving the steps of combining an organodichalcogenide, a metal salt and a ligand compound to form a mixture; degassing the mixture to remove air and water from the mixture; heating the mixture at a temperature below the decomposition temperature of the organodichalcogenide for a period of time sufficient to form a metal chalcogenide nanocrystal.
