Abstract
A process is disclosed for producing quantum dots (QDs) by reacting one or more core semiconductor precursors with phosphine in the presence of a molecular cluster compound. The core semiconductor precursor(s) provides elements that are incorporated into the QD core semiconductor material. The core semiconductor also incorporates phosphorus, which is provided by the phosphine. The phosphine may be provided to the reaction as a gas or may, alternatively, be provided as an adduct of another material.
Claims22
A process of preparing a quantum dot (QD) nanoparticle, the process comprising:
- forming a core semiconductor material on a molecular cluster compound by reacting one or more semiconductor precursors with phosphine in the presence of the molecular cluster compound, wherein the core semiconductor material comprises phosphorus ions and one or more counter ions provided by the semiconductor precursor.
