Abstract

A method for preparing a quantum dot encapsulation body, the preparation method comprising causing a polymerization reaction between ligands on the surface of a plurality of quantum dots to form a whole of the plurality of quantum dots. The quantum dot packaging body prepared by the preparation method of the present invention has better stability, the quantum dots dispersed in the quantum dot packaging body are not easy to agglomerate and have a higher concentration, and the optical performance is better. The invention also provides an electroluminescent device, a backlight unit and a display device.

Description

technical field [0001] The invention relates to a quantum dot packaging body and a preparation method thereof, and also relates to an electroluminescence device and a backlight unit. Background technique [0002] Because quantum dots have the advantages of controllable particle size, uniform dispersion, high excitation conversion efficiency, stability and high light efficiency, they have great application prospects in the field of display devices. The current application and development of quantum dot display devices are mainly divided into photoluminescent devices and electroluminescent devices. Both devices require uniform dispersion of quantum dots in the film. In photoluminescent devices, quantum dots are generally dispersed in polymer materials and encapsulated with glass or barrier film to obtain more stable quantum dots. However, the upper limit of the concentration of quantum dots in polymer materials is generally below 30%, resulting in low overall luminous effici...
