| titleOfInvention | Light-emitting device and preparation method thereof |
| abstract | The present application belongs to the technical field of display devices, and in particular relates to a method for preparing a light-emitting device, comprising the following steps: preparing a light-emitting device comprising an anode, a hole function layer, a quantum dot light-emitting layer, an electron function layer and a cathode that are sequentially stacked; Wherein, the electronic functional layer includes a metal oxide transport material; and the light-emitting device is subjected to ultraviolet light irradiation treatment. In the preparation method of the light-emitting device of the present application, the light-emitting device is subjected to ultraviolet light irradiation treatment, so that the electrons of O in the metal oxide transport material are excited to form complexes with the active metal elements in the quantum dot material, and the metal oxide material is excited by the ultraviolet light. After the fusion with the cathode, the effect is good. The internal physical structure defects and surface roughness of the electron transport layer are reduced, the electron transport and migration efficiency is high, and the quantum dot light-emitting layer is closely combined with the electron transport layer and the cathode interface, and the electron injection efficiency is high, avoiding the accumulation of charges at the interface of the functional layer, and the device stability. Good, long lifespan. |
