有机发光晶体管 (OLET) 将发光和栅极调制电开关功能集成在单个器件中。在过去的几十年里，新型荧光半导体和器件工程的开发取得了进展，将 OLET 器件的效率提高到了 8%。然而，晶体管的这种效率仍然太低，无法与有机发光二极管（OLED）竞争。目前，适用于 OLET 的有机荧光半导体相对较少，并且器件中电致发光的机理仍不完全清楚。在这篇小型评论中，我们讨论了高效 OLET 的状态以及解决这些未解决问题的可行方法。由于这是一篇迷你评论，我们无法涵盖文献中的所有优秀作品。我们鼓励读者阅读之前发表的其他优秀评论。
Organic light-emitting transistors (OLETs) integrate the light-emitting and gate-modulated electrical switching functions in a single device. Over the past decades, progress has been made in developing new fluorescent semiconductors and device engineering that pushed efficiencies of OLET devices to 8%. However, this efficiency of transistors is still too low to be competitive with organic light-emitting diodes (OLEDs). Currently, there are relatively few suitable organic fluorescent semiconductors suitable for OLETs, and the mechanism of electroluminescence in the devices is still not fully understood. In this mini-review, we discuss the state of highly efficient OLETs and plausible approaches to those unsettled problems. Since this is a mini-review, we will not be able to cover all the excellent work in the literature. Readers are encouraged to read other excellent reviews published earlier.
