METHOD FOR PRODUCING CORE/SHELL SEMICONDUCTOR NANOPARTICLES

A method of producing core/shell semiconductor nanoparticles, the method comprising a shell formation step of adding a solution of group VI element precursor while adding a solution of zinc branched chain carboxylate to a core particle-dispersed solution to allow the zinc branched chain carboxylate to react with the group VI element precursor in presence of the core particles for forming a shell containing zinc and the group VI element on surfaces of the core particles. The present invention can provide a simple semiconductor nanoparticle production method of producing core/shell semiconductor nanoparticles with excellent optical properties when two or more types of the shell precursors are used to produce the core/shell semiconductor nanoparticles.
