H2S-induced surface reconstruction enables efficient CsPbI3 QLEDs with ultralow roll-off
Metal halide perovskite quantum dots (QDs) are promising materials for developing low-cost and high-performance quantum dot-based light-emitting diodes (QLEDs). Despite external quantum efficiency (EQE) comparable to II–VI/III–V QLEDs, perovskite QD counterparts achieve peak EQE at low luminance/current density and exh...
