· JVASP-12163· CaPbI4

CaPbI₄ is a halide perovskite ceramic compound containing calcium, lead, and iodine that belongs to the family of metal halide perovskites being actively researched for optoelectronic applications. This material is primarily in the research and development phase rather than established industrial production, with potential applications in next-generation photovoltaic devices, light-emitting systems, and radiation detection where its electronic and optical properties are being explored as alternatives to more conventional semiconductors. The compound's layered structure and compositional flexibility make it of interest to materials scientists investigating how halide perovskites can be tuned for improved stability and performance compared to widely-studied organic-inorganic variants.
