摘要：
Ultraviolet/near ultraviolet （UV/NUV） organic light-emitting diodes （OLEDs） have attracted extensive attention due to its great application potential in biological and chemical sensing， laser， high-density information storage and optoelectronic circuits， etc. This paper reviews the recent development of ultraviolet organic light-emitting diodes （UV-OLEDs）， including organic chromophores， device structures and practical applications. Firstly， the materials with high efficiency shortwave emission are introduced， focusing on the characteristics of the materials themselves and their structural characteristics. Then， we give an overview of device structures to improve the performance of devices. Finally， we discuss the progress and challenges of using UV-OLEDs as excitation sources in emerging applications， and expect that this will promote the development of ultraviolet light sources in more fields in the future. © 2023 Chines Academy of Sciences.
