CsPbBr3

Cesium lead bromide (CsPbBr3) is an inorganic halide perovskite ceramic with a cubic crystal structure, composed of cesium, lead, and bromine ions. This material is primarily investigated in research and emerging technology contexts for optoelectronic applications, particularly as a light-emitting and light-absorbing medium, due to its direct bandgap, high photoluminescence quantum yield, and tunable emission wavelengths across the visible spectrum. While not yet widely deployed in mainstream industrial production, CsPbBr3 is of significant interest to engineers developing next-generation display technologies, solid-state lighting, and radiation detection systems; however, its practical adoption is limited by stability concerns (moisture and thermal sensitivity) and toxicity considerations related to lead content compared to alternative perovskite formulations.
