Abstract

Phosphorescent white organic light-emitting diodes (WOLEDs) employing organometallic phosphors as the emitters have attracted considerable attention in the past decade. Due to their capability of harvesting both singlet and triplet excitons to generate highly efficient devices, phosphorescent WOLEDs present potential applications in the next-generation solid-state lighting sources and in the flat-panel display with the assistance of the color filters. In this chapter, we attempt to give a brief overall introduction to the phosphorescent WOLEDs. The basic concepts, like electric-light conversion efficiency, parameters to assess the color quality of the emissive white light, device strategies to fabricate WOLEDs, and the common device fabrication procedures, are introduced firstly. These fundamental understandings are also favorable to comprehend the monochromatic OLEDs and the WOLEDs comprised of other emitters like fluorescent dyes. In particular, we focus on the discussion of phosphorescent WOLEDs with various device architectures and their corresponding device performances. We also note that further enhancement of the device lifetime with simultaneous realization of high efficiency and high quality of the emissive white light could make phosphorescent WOLEDs promising candidates for the alternative next-generation lighting sources.
