By carefully tuning the thicknesses of low-optical index PEDOT:PSS and high-index ITO layers in organic light-emitting devices (OLEDs), very high optical coupling efficiencies can be obtained through the generation of appropriate microcavity effects. These experiments result in an external quantum efficiency (EQE) of 33.7% for green phosphorescent OLEDs and even higher EQEs of 54.3% can be obtained by adopting an external out-coupling lens.
通过仔细调整有机发光器件 (OLED) 中低光学折射率PEDOT:PSS 和高折射率 ITO 层的厚度，可以通过产生适当的微腔效应获得非常高的光学耦合效率。这些实验导致绿色磷光 OLED 的外量子效率 (EQE) 达到 33.7%，而通过采用外部出射耦合透镜，甚至可以获得更高的 EQE 54.3%。
