Abstract
Tandem white organic light-emitting diodes (WOLEDs) using horizontally oriented phosphorescent dyes in an exciplex-forming co-host are presented, along with an orange OLED. A high external quantum efficiency of 32% is achieved for the orange OLED at 1000 cd m(-2) and the tandem WOLEDs exhibit a high maximum EQE of 54.3% (PE of 63 lm W(-1)).
摘要
本文提出了一种在共主体中使用水平取向磷光染料的串联白色有机发光二极管（WOLED），以及一个橙色 OLED。在 1000 cd m(-2)时，橙色 OLED 的外量子效率达到 32%，串联 WOLED 的最大外量子效率达到 54.3%（功率效率为 63 lm W(-1)）。
