· CsPbF3

CsPbF3 is a halide perovskite ceramic compound composed of cesium, lead, and fluoride ions arranged in a cubic perovskite crystal structure. This material is primarily an experimental research compound under investigation for optoelectronic and photonic applications, particularly as an alternative to more widely studied iodide and bromide perovskites, offering potential advantages in stability and bandgap tuning. While not yet commercialized at scale, CsPbF3 belongs to the broader family of inorganic metal halide perovskites that show promise for next-generation solar cells, scintillators, X-ray detectors, and light-emitting devices where toxicity and environmental concerns demand lead-free or more stable alternatives.
