· JVASP-33824· TmI3

Thulium iodide (TmI₃) is an inorganic ceramic compound belonging to the rare-earth halide family, composed of thulium and iodine. This material is primarily investigated in research and specialized optical applications rather than high-volume industrial production, valued for its potential in infrared optics, laser hosts, and luminescent devices that leverage thulium's unique electronic properties.
