PREPARATION METHODS OF CORE-SHELL NANOPARTICLES AND SOLUTION THEREOF

摘要

Provided are preparation methods of core-shell nanoparticles and solution thereof. The preparation method of a core-shell nanoparticle solution comprises the following steps: adjusting the temperature of a semiconductive nanoparticle solution to a presetting shell layer encapsulating temperature; adding the shell layer precursor solution to the semiconductive nanoparticle solution, and reacting at the presetting shell layer encapsulating temperature, wherein the shell layer precursor solution is formed by mixing zinc salt, alkyl thiol and nonpolar organic solvent; after the reaction carries on for a period of presetting reacting time, the core-shell nanoparticle solution is obtained. The core-shell nanoparticles have the merits of high fluorescence quantum yield, nontoxic, low production cost, and simple process.
