Composite fine particles and method for producing the same

摘要

A method for producing composite fine particles, which comprises one or more growth steps of growing, on surfaces of fine particles of a first Group II-VI compound, layers of a second Group II-VI compound having a bandgap different from that of the first Group II-VI compound and/or having an impurity or impurity concentration different from that of the first Group II-VI compound. This method enables production of composite fine particles of Group II-IV compounds having favorable performances in a simple manner.
