· JVASP-107981· ScI3

Scandium triodide (ScI₃) is an inorganic ceramic compound composed of scandium and iodine, belonging to the rare-earth halide ceramic family. This material is primarily studied in research contexts for optical and electronic applications, particularly as a potential host material for lanthanide-doped luminescent systems and in advanced photonic devices. ScI₃ is notable for its potential in high-refractive-index optical materials and as a precursor compound in scandium-based ceramic synthesis, though industrial-scale applications remain limited compared to more established ceramic systems.
