LuF3

Lutetium trifluoride (LuF₃) is an inorganic ceramic compound belonging to the rare-earth fluoride family, characterized by its high ionic bonding and luminescent properties. It is primarily investigated for optical and photonic applications, particularly in laser systems, scintillation detectors, and upconversion materials for medical imaging and solid-state lighting. LuF₃ is notable among rare-earth fluorides for its thermal stability and potential use in high-energy physics instrumentation and next-generation optical devices, though it remains more of a research and specialized-application material compared to broader-use ceramics.
