Abstract
The present application discloses a method for modifying zinc oxide nanoparticles, comprising following steps: obtaining zinc oxide solution and betaine ligands; mixing the zinc oxide solution and the betaine ligand, keeping a resulting mixed solution reacted under a protective gas atmosphere at a preset temperature, and separating a modified zinc oxide from the resulting mixed solution to obtain a modified zinc oxide. The method for modifying zinc oxide nanoparticles provided in the present application is simple and quick to operate, suitable for industrial production and meets application requirements. And the modified zinc oxide with betaine ligands grafted on the surface has good stability and excellent monodisperse performance, hinders the transmission rate of electrons to a certain extent and improves the recombination efficiency of electrons and holes in the quantum dot light-emitting layer.
