| 中文摘要 | by wisely utilizing combinations of exciton-managed orange-phosphorescence/sky blue fluorescence, we report on high-efficiency white organic light-emitting diodes (woleds) with high color-stability together with reduced efficiency roll-off. two woleds with the peak current efficiencies of 34.5 and 42.5 cd a (1) which slightly shift to 34.2 and 40.0 cd a (1) at 1000 cd m (2) are demonstrated. systematic investigations focused on the effects of hole-injection buffer layer, thickness of emitting-layer (eml) and the stepwise-doping profile of orange phosphorescent eml on the device performance have been performed. it is evidently shown that careful management of the triplet/singlet excitons and charge-carriers is key to realizing such high performance of the devices. the results will beyond doubt be helpful to the design of both material and device structure for high-performance woleds and next-generation solid-state lighting sources.
