摘要
紫外/近紫外(UV/NUV)有机电致发光二极管(OLEDs)因在生物、化学传感、激光、高密度信息存储和光电子电路等方面的巨大应用潜力,吸引了科研人员的广泛关注。本文综述了紫外/近紫外有机电致发光二极管(UV/NUV-OLEDs),包括有机发色团、器件结构到实际应用的最新研究进展。首先,介绍了具有高效短波发射的紫外和近紫外发光材料,重点介绍了材料本身的特征及其结构特点;随后,总结了有利于提高设备性能的器件结构;最后,讨论了在新兴应用中使用UV/NUV-OLEDs作为激发源的进展和挑战,期待为促进紫外光源在未来更多领域应用中的开发提供一定的借鉴。
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.
