· JVASP-59552· SmF3

SmF₃ (samarium trifluoride) is an ionic ceramic compound belonging to the rare-earth fluoride family, characterized by a perovskite-related crystal structure. This material is primarily investigated for optical and photonic applications where its transparent fluoride matrix and rare-earth dopant compatibility enable function as a host medium for laser crystals and luminescent devices. SmF₃ is notably used in specialized contexts such as solid-state laser systems, optical coatings, and scintillator research, where its fluoride chemistry provides superior transparency in the infrared and ultraviolet ranges compared to oxide ceramics, though it remains less common in mainstream industrial production than established fluoride competitors like CaF₂ or YF₃.
