Observation of transient emission in organic light-emitting devices

为了评价有机发光器件的工作机理，研究了插入光载流子生成层的有机发光器件的直流和瞬态响应特性。通过优化载流子生成层和器件结构，观察到光照射下电流密度的增强。此外，电流的瞬态响应表明在有机/金属界面处有载流子注入。

For evaluation of operation mechanisms of the organic light-emitting devices (OLEDs), DC and transient response characteristics of OLEDs inserted a photo carrier generation layer were examined. Enhancement of current density under photo irradiation was observed by optimization of carrier generation layer and device structure. In addition, transient response of current was observed to suggest carrier injection at organic/metal interface.
