TmBr3

Thulium tribromide (TmBr₃) is an inorganic ceramic compound composed of the rare-earth element thulium and bromine, belonging to the halide ceramic family. This material is primarily of research and specialized laboratory interest rather than widespread industrial production, with applications centered on optical, photonic, and materials science research where rare-earth halides serve as host materials for luminescent dopants and solid-state laser systems. TmBr₃ is notable within rare-earth halide ceramics for its potential in infrared optics and upconversion phosphors, though it remains largely confined to academic and developmental contexts rather than high-volume engineering applications.
