ceramic

· JVASP-53161· RbBiF3

RbBiF3 is a halide perovskite ceramic compound composed of rubidium, bismuth, and fluorine. This material belongs to the family of lead-free perovskites currently under active research for optoelectronic and photovoltaic applications, where it offers potential advantages in stability and reduced toxicity compared to lead-based alternatives. While primarily in the experimental phase, RbBiF3 is being investigated for next-generation solar cells, scintillators, and radiation detectors due to the favorable electronic properties of bismuth-based compounds and the chemical stability afforded by fluoride bonding.
