Inverted Quantum-Dot Light-Emitting Diodes Fabricated by All-Solution Processing

Abstract

PSS is reduced by using isopropanol as the additive. With optimized conditions, the demonstrated QD-LEDs exhibit a maximum luminance of 16290 cd/m(2) and a peak current efficiency of 4.1 cd/A, which is the highest among the reported values. These results may offer a practicable platform for further research, leading to the achievement of all-solution processed, multilayer, and efficient inverted QD-LEDs.
