· JVASP-5266· Sr2InI5

Sr2InI5 is a mixed-metal halide ceramic compound belonging to the family of strontium-indium iodides, which are primarily investigated in materials science research rather than established in commercial production. This material is of interest in the optoelectronics and solid-state chemistry communities as a potential photovoltaic absorber, scintillator, or radiation detector material, exploiting the high atomic number of indium and iodine for photon interaction. Sr2InI5 represents an alternative to lead-based halide perovskites, offering potential advantages in chemical stability and reduced toxicity while maintaining semiconducting properties relevant to light-emitting and light-absorbing device architectures.
