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.

高性能有机发光晶体管的设计。

有机发光晶体管（OLET）将发光和栅极调制的电开关功能集成在单个设备中。在过去的几十年中，在开发新型荧光半导体和器件工程方面取得了进展，这使OLET器件的效率提高到8％。但是，晶体管的效率仍然太低而不能与有机发光二极管（OLED）竞争。当前，适用于OLET的有机荧光半导体相对较少，并且器件中的电致发光机理仍未完全理解。在此小型审查中，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。由于这是一篇简短的综述，因此我们将无法涵盖文献中的所有出色著作。
