· Y1 Bi2 I1 O4

Y₁Bi₂I₁O₄ is an experimental bismuth-based mixed-halide oxide semiconductor combining rare-earth (yttrium) and heavy-metal (bismuth) elements with iodine and oxygen. This compound belongs to the family of halide perovskites and perovskite-like semiconductors, which are actively researched for optoelectronic applications due to their tunable bandgaps and potential for solution-based manufacturing. The material is primarily of research interest rather than established industrial production, with potential applications in photovoltaic devices, photodetectors, and X-ray imaging where bismuth's high atomic number and iodide's strong light absorption are advantageous.
