Abstract

The invention discloses a light-emitting device and a preparation method thereof. The light-emitting device comprises, from the bottom up, a substrate, a pixel electrode, a light-emitting layer, a charge transport layer and a top electrode, wherein the upper surface of the charge transport layer is distributed by metal nanoparticles. By blending the metal nanoparticles with the charge transport material, the metal nanoparticles are gathered on the surface of the charge transport layer of the light-emitting device, thereby realizing control of space between the metal nanoparticles and the light-emitting layer easily and effectively, and furthermore, improving the performance of the light-emitting device by effectively utilizing a surface plasma enhancement effect of the metal nanoparticles.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a light-emitting device and a preparation method. Background technique [0002] In the contemporary age of the information society, the importance of displays as a visual information transmission medium is further enhanced, and in order to dominate in the future, displays are moving towards lighter, thinner, lower power consumption, lower cost and better image quality trend development. [0003] Organic electroluminescent diodes (OLEDs) have the advantages of self-luminescence, fast response, wide viewing angle, high brightness, and thinness, and their potential market prospects are favored by the industry. Quantum dot light-emitting diodes (QLEDs) have become a strong competitor of OLEDs in recent years due to their high light color purity, high luminescence quantum efficiency, and easy tunability of luminescence colors. Therefore, these two display technologies ...
