摘　　要：碳基有机半导体光电器件,特别是有机发光二级管(OLED),易于从分子层级进行调控设计,近年来已经逐步实现产业化。由于OLED元器件所制造的产品价格较为昂贵,以及OLED器件的结构和制备工艺复杂且使用寿命不够长和效能还有待提高,因此研究如何能够降低能耗、简化结构、提高稳定性,对于推广OLED器件具有重要意义。综述了3类新型OLED器件结构,即超薄发光体OLED、叠层OLED和激基复合物主体OLED的研究进展,并对不同结构的特点和优劣势进行了分析总结,这对推动器件结构研发和科研思路启发起到积极作用。Carbon-based organic semiconductor optoelectronic devices,especially the organic light-emitting diode(OLED),are easy to be regulated and designed from the molecular level,and have been gradually industrialized in recent years.However,the price of products manufactured based on OLED is still relatively expensive,mainly because its complex structure and fabrication process,as well as insufficient service life and performance.Therefore,it is of great significance to study how to reduce energy consumption,simplify structure and improve stability for the promotion of OLED devices.In this paper,the research progress of three new OLED devices(Ultra-thin emitting OLEDs,Tandem OLED,and Exciplex host OLED)is reviewed,and the characteristics as well as their respective advantages and disadvantages are summarized.This paper can play a positive role in promoting the research and development of device structures and inspiring scientific research ideas.
