Abstract
Abstract A high efficiency blue phosphorescence organic light emitting device (OLED) was demonstrated by using a novel electron transporting and wide band gap material, CbzTAZ, as host doping with blue emitter, iridium(III)bis[4,6‐(di‐fluorophenyl)‐pyridinato‐N, C2′]picolinate (FIrpic). By adjusting the doping ratio of FIrpic and the thickness of emitting layer, we obtained an efficient blue phosphorescence OLED with high current efficiency over 45 cd/A and high external quantum efficiency over 23%.
