Water-soluble quantum dots, manufacturing method thereof and manufacturing method of quantum dot thin film

摘要

In a water-soluble quantum dot, a manufacturing method, and a method of manufacturing a quantum dot thin film, the method provides a soluble quantum dot and a polymercapto group polymer, respectively, and under the protection of an inert gas, reacts the polymercapto group polymer with a soluble quantum dot to react for ligand exchange Proceeding, adding an appropriate amount of water, and collecting the upper aqueous solution after the reaction, the step of preparing a water-soluble quantum dot, wherein the polymercapto group polymer dissolves the polymer having amino groups and epithioalkanes in anhydrous chloroform , Obtained by reacting under a first predetermined condition. The manufacturing method can obtain stable water-soluble quantum dots, and can maintain the optical performance of intrinsic quantum dots. A quantum dot thin film can be conveniently manufactured through LBL technology by using a water-soluble quantum dot that has a charge.
