Water-soluble quantum dot, manufacturing method therefor and manufacturing method for quantum dot films

摘要

The present invention discloses a type of water-soluble quantum dot, a manufacturing method thereof and a manufacturing method of quantum dot films, wherein the water-soluble quantum dots manufacturing method comprises: providing oil-soluble quantum dots and polythiol polymers, respectively; Mixing and reacting the polythiol polymers and an oil-soluble quantum dot under the protection of inert gas to effect ligand exchange; Add an appropriate amount of water and collect the reacted upper layer of the aqueous solution to obtain water-soluble quantum dots. In the manner of the invention described above, stable water-soluble quantum dots can be obtained while retaining the original optical properties of the quantum dots. By using the water-soluble quantum dots with electric charge, quantum dot films can be easily produced by the LbL technique.
