19.3: Efficient White Phosphorescent Organic Light‐Emitting Devices

Abstract
We demonstrate two phosphorescent white OLEDs. At 1,000 cd/m2, one has EQE = 20% at CIE = (0.38, 0.39), and another has 25 lm/W with CIE (0.39, 0.44). At 100 cd/m2and with outcoupling enhancements, devices either have total EQE = 37% or total efficacy = 51 lm/W.
