摘要：

In this work, we demonstrate single-emitting-layer hybrid white organic light-emitting diodes (WOLEDs) with high-efficiency and low efficiency roll-off. Here, the white emission arises from stable blue emission via elec-troluminescence (EL) spectral shift from green thermally activated delayed fluorescence (TADF) emitter and yellow phosphorescent emitter. WOLEDs shows a maximum current efficiency of 56.77 cd/A, maximum power efficiency of 50.19 lm/W, and maximum external quantum efficiency of 20.00%. Compared to the devices composed of conventional blue TADF emitters, the device based on EL sp...
