Low‐Driving‐Voltage Blue Phosphorescent Organic Light‐Emitting Devices with External Quantum Efficiency of 30%
Source abstract
Abstract
A homoleptic iridium (iii) tris(pheny-limidazolinate) complex realizes a high EQE of 30%, a low turn-on voltage of 2.5 V, and a small efficiency roll-off in a blue organic light-emitting device (OLED). This device also shows high power efficiencies over 75 lm W(-1) and an ideal light distribution pattern at 100 cd m(-2).
