METHOD FOR PREPARING SEMICONDUCTOR NANOCRYSTALS

摘要

A method for making semiconductor nanocrystais is disclosed, the method comprising adding a secondary phosphine chalcogenide to a solution including a metal source and a liquid medium at a reaction temperature to form a reaction product comprising a semiconductor comprising a metal and a chalcogen, and quenching the reaction mixture to form quantum dots. Methods for overcoating are also disclosed. Semiconductor nanocrystais are also disclosed.
