Cs1 Pb1 F3

CsPbF₃ is a halide perovskite semiconductor compound composed of cesium, lead, and fluorine. This material is primarily investigated in research settings as a candidate for next-generation optoelectronic devices, particularly in photovoltaics, light-emission applications, and radiation detection, where its wide bandgap and stability characteristics offer potential advantages over the more widely studied iodide and bromide perovskites. The fluoride variant is notable for its enhanced phase stability and reduced toxicity concerns compared to lead-iodide perovskites, though commercial deployment remains limited and the material is best considered an emerging technology in the perovskite family rather than a mature engineering solution.
