Besides the flourishment in photovoltaics, halide perovskites hold great promise to compete with leading contenders among solution-processed emitters, such as organics and semiconductor colloidal nanocrystals, in the field of light emission. Halide perovskites exhibit outstanding optoelectronic properties, including high photoluminescence quantum yields, facile bandgap tunability, narrow emission line widths, and respectable carrier mobilities, promoting them to thrive in versatile light-emitting applications such as light-emitting diodes, lasers, X-ray scintillators, and circularly polarized light sources. Herein, we discuss the underlying physics of light emission in state-of-the-art perovskite light-emitting devices and focus on promising strategies for further improvement of device performance.
