Beschreibungen/Notizen

• 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).
