Na3TmBr6

Na₃TmBr₆ is an inorganic halide ceramic composed of sodium, thulium, and bromine—a rare-earth bromide compound that exists primarily in research and development contexts. This material belongs to the family of lanthanide halide perovskites and related structures, which are of interest in optoelectronics, scintillation, and solid-state lighting applications due to rare-earth luminescent properties. While not yet commercialized at scale, compounds in this family are investigated for their potential in photonic devices, X-ray detectors, and high-efficiency light sources where rare-earth dopants or hosts are strategically exploited.
