Abstract

Abstract: We have developed phosphorescent OLEDs utilizing energy transfer from an exciplex to an emitter. The OLEDs based on this mechanism showed quite high efficiency, a long lifetime and low drive voltage. OLED lighting with high power efficiency exceeding 100 lm/W at a practical luminance of 5, 000 cd/m 2 was also successfully developed.
