Ba2SrI6 is an inorganic ceramic compound belonging to the double-halide perovskite family, composed of barium, strontium, and iodine. This is a research-phase material under investigation primarily for optoelectronic and photonic applications, particularly as a lead-free alternative in halide perovskite semiconductors where stability and non-toxicity are critical design requirements. The material's layered double-halide structure positions it as a candidate for next-generation radiation detection, photovoltaic devices, and scintillator applications where conventional lead-based perovskites face regulatory or environmental constraints.
