Abstract
Disclosed herein is a method for the preparation of metal phosphide nanocrystals using a phosphite compound as a phosphorous precursor. More specifically, disclosed herein is a method for preparing metal phosphide nanocrystals by reacting a metal precursor with a phosphite compound in a solvent. A method is also provided for passivating a metal phosphide layer on the surface of a nanocrystal core by reacting a metal precursor with a phosphite compound in a solvent. The metal phosphide nanocrystals have uniform particle sizes and various shapes.
