Abstract:
1. A method of forming monodisperse metal chalcogenide nanocrystals without precursor injection, comprising the steps of: combining a metal source, a chalcogen oxide or a chalcogen oxide equivalent, and a fluid comprising a reducing agent in one pot at a first temperature to form a liquid comprising assembly; increasing the temperature of said assembly to a sufficient-temperature to initiate nucleation to form a plurality of metal chalcogenide nanocrystals, and growing said plurality of metal chalcogenide nanocrystals without injection of either said metal source or said chalcogen oxide at a temperature equal to or greater than said sufficient-temperature, wherein crystal growth proceeds substantially without nucleation to form a plurality of monodisperse metal chalcogenide nanocrystals.
