Chemically synthesized lead halide perovskite nanocrystals have recently emerged as a new class of efficient light emitting materials. High emission quantum yield, easily tuned emission colors, and high color purity make this class of materials particular attractive for light-emitting devices (LEDs) and display applications. I will review some of our recent synthetic strategies leading to highly luminescent perovskite nanocrystals of different sizes and shapes, and doping strategies we use to improve their stability. I will discuss the design of core-shell perovskite nanocrystals for LEDs with low efficiency roll-off, and provide examples of rather efficient charge injection LEDs based on either perovskite nanocrystals or thin perovskite films.
