Abstract

An extremely high-efficiency solution-processed white organic light-emitting diode (WOLED) is successfully developed by simultaneously using an ideal dendritic host material and a novel efficient orange phosphorescent iridium complex. The optimized device exhibits forward-viewing efficiencies of 70.6 cd A−1, 26.0%, and 47.6 lm W−1 at a luminance of 100 cd m−2, respectively, promising the low-cost solution-processed WOLEDs a bright future as the next generation of illumination sources.
