论文摘要
有机发光二极管（OLEDS）取得了很大的进步，以实现高外部量子效率（EQE），其中OLED发射器的偶极取向具有显着效果。在大多数情况下，OLED发射极的EQE从理论上预测，只有一个取向因子与相应的实验匹配。在这里，我们开发了具有三个独立参数的分布理论，以充分描述偶极子方向和功率密度之间的关系。此外，我们提出了一种用于测量此类分布参数的最佳实验配置。测量非极化光谱可以以一种相当简单的方式挖掘更多偶极子方向分布的信息。我们的理论提供了OLED偶极子方向的普遍情节，为设计更复杂的OLED结构铺平了道路。
Considerable progress has been made in organic light-emitting diodes (OLEDs) to achieve high external quantum efficiency (EQE), among which the dipole orientation of OLED emitters has a remarkable effect. In most cases, EQE of the OLED emitter is theoretically predicted with only one orientation factor to match with corresponding experiments. Here, we develop a distribution theory with three independent parameters to fully describe the relationship between dipole orientations and power densities. Furthermore, we propose an optimal experiment configuration for measuring such distribution parameters. Measuring the unpolarized spectrum can dig more information of dipole orientation distributions with a rather simple way. Our theory provides a universal plot of the OLED dipole orientation, paving the way for designing more complicated OLED structures.
