· Rb2PbCl6

Rb2PbCl6 is a halide perovskite ceramic compound composed of rubidium, lead, and chlorine. This material belongs to the family of inorganic halide perovskites, which are currently the subject of intensive research for optoelectronic and photonic applications due to their tunable bandgap and crystalline stability. While not yet widely deployed in mainstream industrial production, rubidium lead chloride perovskites show promise as alternatives to organic-inorganic hybrid perovskites in applications requiring improved thermal and chemical stability.
