Metal halide perovskite nanomaterials emerged as attractive emitting materials for light-emitting diodes (LEDs) devices due to their high photoluminescence quantum yield (PLQY), narrow bandwidth, high charge-carrier mobility, bandgap tunability, and facile synthesis. In the past few years, it has been witnessed an unprecedented advance in the field of metal halide perovskite nanomaterials based LEDs (PeLEDs) with a rapid external quantum efficiency (EQE) increase from 0.1% to 14.36%. From the viewpoint of material chemistry, the chemical regulation of metal halide perovskite nanomaterials made a great contribution to the efficiency improvement of PeLEDs. In this review, we categorize the strategies of chemical regulation as A-site cation engineering, B-site ion doping, X-site ion exchange, dimensional confinement, ligand exchange, surface passivation and interface optimization of transport layers for improving the EQEs of PeLEDs. We also show the potentials of chemical regulation strategies to enhance the stability of PeLEDs. Finally, we present insight toward future research directions and an outlook to further improve EQEs and stabilities of PeLEDs aiming to practical applications.
