· Bi4I

Bi4I is a bismuth iodide ceramic compound belonging to the halide perovskite family, characterized by a layered crystal structure combining bismuth cations with iodide anions. This material is primarily of research and developmental interest for optoelectronic and photovoltaic applications, particularly as a lead-free alternative in perovskite solar cells and as a potential scintillator or X-ray detector material. Bismuth halides offer stability advantages over lead-based perovskites and are being investigated for their photoluminescence and radiation-sensing properties, making them candidates for next-generation imaging and energy conversion technologies.
