METHOD FOR PREPARING CORE/SHELL STRUCTURE NANOPARTICLES

摘要

A method for preparing core/shell-structure nanoparticles is provided to be insensitive to change in a reaction condition and produce the core/shell-structure nanoparticles rapidly and reproducibly. A method for preparing core/shell-structure nanoparticles includes the steps of: (1) dissolving a shell precursor in a reaction solvent to prepare a shell precursor solution, and then stabilizing the shell precursor solution at sufficient temperature to overcoat a core surface with the shell precursor; and (2) injecting core nanoparticles into the stabilized shell precursor solution. In the step (1), the shell precursor solution is stabilized at 100-250°C. A concentration of the shell precursor in the shell precursor solution prepared in the step (1) is 0.05-1.0M.
