Highly Efficient Orange and White Organic Light-Emitting Diodes Based on New Orange Iridium Complexes

Highly efficient, orange organic light‐emitting diodes (OLEDs) fabricated from newly synthesized iridium complexes show a maximum luminance efficiency of 76 cd A−1 and a peak power efficiency of 45 lm W−1. The white OLEDs containing the orange iridium and traditional blue iridium phosphors exhibit e...

Zusammenfassung:Highly efficient, orange organic light‐emitting diodes (OLEDs) fabricated from newly synthesized iridium complexes show a maximum luminance efficiency of 76 cd A−1 and a peak power efficiency of 45 lm W−1. The white OLEDs containing the orange iridium and traditional blue iridium phosphors exhibit extraordinarily high efficiencies and a peak external quantum efficiency of 26%.
