Abstract

High performance three-color hybrid white organic light-emitting diode (WOLED) has been demonstrated by emissions from a fluorescent blue emitter 5,11-di(40-dimesitylboronphenyl) indolo[3,2-b]carbazole (DDBICZ), a phosphorescent yellow emitter bis(2-(3-trifluoromethyl-4-fluorophenyl)-4-methylquinolyl) (acetylacetonate) iridium(III) (Ir(ffpmq)₂(acac)) and a phosphorescent red emitter bis(1-phenylisoquinoline) (acetylacetonate) iridium(III) (Ir(piq)₂(acac)). The blue emitting DDBICZ in the device also acts as a host for Ir(ffpmq)₂(acac) and Ir(piq)₂(acac) dopants. The emissive layer in the DDBICZ-based hybrid WOLEDs consists of a sequential symmetric doping configuration for achieving high color stability, CIE color coordinates of (0.40, 0.41) and color rendering index of 86 over the brightness range from 10 cd/m² to 10,000 cd/m². The hybrid WOLEDs thus developed also possess a high lumious efficiency of 25.9 cd/A.
