Cs₂NaBiF₆ is a double perovskite ceramic compound composed of cesium, sodium, bismuth, and fluorine. This halide perovskite material is primarily investigated in research contexts for optoelectronic and photonic applications, particularly as a lead-free alternative in scintillator and luminescent device development. Its notable advantage over conventional perovskites is the absence of toxic lead, combined with potential for tunable optical properties, making it of interest where environmental regulations or biocompatibility requirements restrict lead-based materials.
