Abstract

Abstract:

Perovskite quantum dots have unique advantages in display. However, their long-term stability at high brightness is still a huge challenge. Therefore, this article focuses on the progress of the regulation of perovskite quantum dots and their luminescent film morphology, explains the influence of long-range ordered perovskite quantum dot films on their electroluminescent properties, and looks forward to the development prospects in improving the electroluminescent stability of perovskite quantum dots.

Key words: perovskite quantum dot, long-range ordering, ligand exchange, display material, quantum dot light- emitting diode

CLC Number:

TQ174
