基于OLED显示单元的红外上转换器件研究进展

Recent progress of infrared upconversion device based on the integration of OLED

综述了不同类型上转换器件的的研究进展,包括性能优化、器件集成以及物理机制。其中基于OLED的红外上转换器件将红外探测器与OLED串联集成起来,使近红外光首先被吸收,进而光生电流驱动OLED产生可见光,可完成近红外-可见光上转换功能。该项研究拓展了OLED在红外夜视方面的应用。

This paper presents recent research and development effort in realizing and perfecting the infrared upconversion device , and mainly focuses on the design optimization , device integration and internal semiconductor physics of different optical up-conversion device structures .The upconversion idea relies on the integration of a photodetector and an organic light-emitting device（OLED）.The infrared is first absorbed by photodetector part , and then the photocurrent would drive the OLED to emit visible light , which functions as infraredto-visible upconversion .This research enhanced the application of OLED in infrared imaging .
