O8 Na2 I2

Na₂I₂O₈ is an inorganic compound belonging to the halide-oxide semiconductor family, combining sodium, iodine, and oxygen into a structured crystalline material. This composition is primarily of research interest for next-generation semiconductor and optoelectronic applications, particularly in contexts where halide perovskites and mixed-anion systems are explored for photovoltaic devices, scintillation detectors, or solid-state ionics; it represents an emerging materials chemistry space rather than an established industrial standard, with potential advantages in tunable bandgap and ionic conductivity compared to pure halide alternatives.
