Abstract	Metal halide perovskites (MHPs) are exceptional semiconductorsbest known for their intriguing properties, such as high absorptioncoefficients, tunable bandgaps, excellent charge transport, and highluminescence yields. Among various MHPs, all-inorganic perovskitesexhibit benefits over hybrid compositions. Notably, critical properties,including chemical and structural stability, could be improved byemploying organic-cation-free MHPs in optoelectronic devices suchas solar cells and light-emitting devices (LEDs). Due to their enticingfeatures, including spectral tunability over the entire visible spectrumwith high color purity, all-inorganic perovskites have become a focusof intense research for LEDs. This Review explores and discusses theapplication of all-inorganic CsPbX3 nanocrystals (NCs)in developing blue and white LEDs. We discuss the challenges perovskite-basedLEDs (PLEDs) face and the potential strategies adopted to establishstate-of-the-art synthetic routes to obtain rational control overdimensions and shape symmetry without compromising the optoelectronicproperties. Finally, we emphasize the significance of matching thedriving currents of different LED chips and balancing the aging andtemperature of individual chips to realize efficient, uniform, andstable white electroluminescence.
