· JVASP-12480· RbPb2Br5

RbPb₂Br₅ is an inorganic halide perovskite ceramic compound containing rubidium, lead, and bromine. This material belongs to the family of metal halide perovskites, which are primarily investigated for optoelectronic and photovoltaic applications rather than structural engineering use. The compound is of research interest due to its potential semiconducting and light-emitting properties, though it remains largely in the experimental phase and has not achieved widespread industrial adoption compared to more stable perovskite variants.
