Adding solid electrolytes into organic semiconductors broadens the scope of material properties and electronic applications. Successful examples include polymer light-emitting electrochemical cells, electrolyte-gated organic transistors, and electrolyte-gated organic light-emitting transistors (EGLETs). EGLETs combine an organic light-emitting device and a transistor with a high capacitance electrolytic dielectric. Here we summarize recent progress in the development of EGLETs in both planar and vertical device architectures. The former offers a lateral geometry and in-plane light-emission for scientific scaffolds in the fundamental study of organic semiconductor opto-physics. The latter features surface emission with a unity aperture ratio, and it can be used in matrix displays without the requirement of external thin-film transistor arrays as the switching circuitry. This strategy paves an easy avenue towards fabricating highly integrated organic optoelectronic devices, and it offers a new test bed for research in iontronics and organic electronics.

电解质门控发光晶体管：工作原理和应用

在有机半导体中添加固体电解质拓宽了材料性能和电子应用的范围。成功的示例包括聚合物发光电化学电池，电解质门控有机晶体管和电解质门控有机发光晶体管（EGLETs）。EGLET将有机发光器件和具有高电容电解电介质的晶体管结合在一起。在这里，我们总结了在平面和垂直设备体系结构中EGLET的开发方面的最新进展。前者为有机半导体光物理基础研究中的科学支架提供了横向几何形状和面内发光。后者的特征是具有统一的孔径比的表面发射，它可以用于矩阵显示器，而无需外部薄膜晶体管阵列作为开关电路。该策略为制造高度集成的有机光电器件铺平了道路，并且为离子电子学和有机电子学的研究提供了新的测试平台。
