Abstract

The invention discloses a preparation method of a quantum point, an application method and a quantum point product, and relates to the technical field of the quantum point. The quantum point is applied to a quantum point solution, water oxygen molecules and other quantum point molecule are prevented from invading into quantum point nucleus, so that the glowing effect and the glowing efficiency ofthe quantum point are improved. The main technical scheme of the invention is the preparation method of the quantum point, and the preparation method comprises the following steps: firstly, dissolvinga quantum point sample into an organic solvent to obtain a sample solution; then dissolving a reticular ligand into the sample solution to obtain the quantum point with the reticular ligand. The preparation method of the quantum point, the application method and the quantum point product disclosed by the invention are mainly used for storing the quantum point.

Description

technical field [0001] The invention relates to the technical field of quantum dots, in particular to a method for preparing quantum dots, an application method and quantum dot products. Background technique [0002] Quantum dot is a kind of semiconductor nanocrystal, which has unique luminous characteristics and can be widely used in the field of optoelectronic technology. Among them, quantum dot light-emitting diode display is a display device prepared by using quantum dots as a light-emitting layer. Quantum dot light-emitting diodes have With the advantages of high color gamut and fast response speed, quantum dot materials commonly used in quantum dot light-emitting diodes include cadmium-based quantum dots, perovskite quantum dots, indium phosphide quantum dots, copper indium sulfur quantum dots, etc. [0003] However, since the quantum dot core of the quantum dot is not protected by the shell, when the quantum dot material is preserved, the water and oxygen molecules in...
