Zwitterionic additive for high-performance pure-blue perovskite light-emitting diodes
Abstract
Despite the significant advancements in perovskite light-emitting diodes (PeLEDs), achieving high-performance blue LEDs remains a key concern for future display and optical communication applications, particularly pure-blue PeLEDs with high external quantum efficiency (EQE) and luminance. Recently, Hou and colleagues reported the utilization of an efficient additive that enables stable emission color with an enhanced EQE of 9.25% and a maximum luminance of 1806 cd cm-2, representing one of the best-performing pure-blue PeLEDs.
