Abstract

Lead halide perovskite nanocrystals are currently under intense investigation as components of solution-processed light-emitting devices (LEDs). We demonstrate LEDs based on Ag doped–passivated CsPbI 3 perovskite nanocrystals with external quantum efficiency of 11.2% and an improved stability. Ag an...
