摘要:
An OLED device comprises a cathode, an anode, and has therebetween a light-emitting layer containing a phosphorescent emitter that emits yellow, orange or red light; a tertiary arylamine compound as a first host material, and a gallium complex with only nitrogen bidentate ligands as a second host material. Desirably, the phosphorescent emitter is an iridium complex.
