METHOD FOR SYNTHESIZING CORE/SHELL NANOPARTICLES AND THEIR SOLUTION

摘要

The present invention provides a method for synthesizing core/shell nanoparticles and their solution. A method for synthesizing a core/shell nanoparticles solution, comprising the steps of: adjusting the temperature of a semiconductor nanoparticles solution to a predetermined coating temperature; adding a shell precursor solution into the semiconductor nanoparticles solution and reacting at the predetermined coating temperature, the shell precursor solution being mixed with components comprising zinc salt, alkanethiol and nonpolar organic solvent; after a predetermined reaction time, obtaining the core/shell nanoparticles solution. The core/shell nanoparticles obtained in this invention are characterized by a high quantum yield, a low toxicity, a low production cost and a simple process.
