TbF3

Terbium fluoride (TbF₃) is an ionic ceramic compound belonging to the rare-earth fluoride family, combining a lanthanide element with fluorine. It is primarily investigated for optical and photonic applications, particularly in laser systems, upconversion materials, and specialized optical coatings where its rare-earth luminescent properties are leveraged. TbF₃ is less commonly used in high-volume industrial production compared to more established ceramics, but represents a research-focused material for engineers developing advanced photonic devices, scintillators, and high-performance optical components where rare-earth fluorides offer unique refractive and fluorescence characteristics unavailable in conventional materials.
