High-efficiency and low-efficiency roll-off fluorescence/phosphorescence hybrid white organic light-emitting diodes based on AIEgens with hot exciton property by strategically managing triplet excitons

OLEDs with efficient blue emission are fabricated using AIE materials. Utilizing TPB-AC enables high-efficiency two-color white OLEDs, and introducing a TTF layer significantly enhances the efficiency, the maximum efficiency increased to 23.2%.
