Metal halide perovskites have drawn significant interest in the past decade. Superior optoelectronic properties, such as a narrow bandwidth, precise and facile tunable luminance over the entire visible spectrum, and high photoluminescence quantum yield of up to ≈100%, render metal halide perovskites suitable for next-generation high-definition displays and healthy lighting systems. The external quantum efficiency of perovskite light-emitting diodes (LEDs) increases from 0.1 to 11.7% in three years; however, the energy conversion efficiency and the long-term stability of perovskite LEDs are inadequate for practical application. Strategies to optimize the emitting layer and the device structure, with respect to material design, synthesis, surface passivation, and device optimization, are reviewed and highlighted. The long-term stability of perovskite LEDs is evaluated as well. Meanwhile, several challenges and prospects for future development of perovskite materials and LEDs are identified. Fascinating metal halide perovskite nanomaterials bring a revolution in the field of displays and lighting. Strategies toward high performance perovskite light-emitting diodes (LEDs) concerning the optimization of emitting materials and device structures are reviewed. The long-term stability of perovskite LEDs are discussed as well. Challenges and prospects that are crucial for the development of perovskite materials and LEDs are identified.
