Progress of organic light-emitting transistors

有机发光晶体管(organic light-emitting transistors,OLETs)是一类新型的有机光电子器件,它们集成了有机场效应晶体管(organic field-effect transistors,OFETs)的开关功能和有机发光二极管(organic light-emitting diodes,OLEDs)的发光功能,在光通讯领域、平板显示、固体照明以及激光领域展现出潜在的应用前景,同时也为研究有机半导体中的载流子注入、传输、复合等物理过程提供了一个优秀的测试系统.在介绍OLETs基本器件结构的基础上,重点总结了OLETs最新研究进展,最后展望了OLETs的应用和前景.

Organic light-emitting transistors （OLETs） are a new class of organic optoelectronic devices which combine the electrical switching functionality of organic field-effect transistors （OFETs） and the light-emission of organic light-emitting diodes （OLEDs） in a single device, and these devices have potential applications in optical communication systems, flat panel display, solid state lighting and electrically-pumped organic lasers. Meanwhile, the OLETs offer an ideal structure for investigating fundamental optical and electronic properties of carrier in organic semiconductors such as injection, transport and recombination. On the basis of the introduction of the device structure of OLETs, we review the advances in OLETs. Finally, we prospect the application of OLETs and their challenges.
