The past two years have witnessed heightened interest in metal-halide perovskites as promising optoelectronic materials for solid-state light emitting applications beyond photovoltaics. Metal-halide perovskites are low-cost solution-processable materials with excellent intrinsic properties such as broad tunability of bandgap, defect tolerance, high photoluminescence quantum efficiency and high emission color purity (narrow full-width at half maximum). In this review, the photophysical properties of hybrid perovskites, which relates with light-emission, such as broad tunability, nature of the recombination processes and quantum efficiency are examined. The prospects of hybrid perovskite light-emitting diodes and lasers, and their key challenges are also discussed.
