· JVASP-33828· LuI3

Lutetium triiodide (LuI₃) is an inorganic ceramic compound composed of the rare-earth element lutetium and iodine, belonging to the rare-earth halide family. This material is primarily of research and specialized application interest, valued for its optical and luminescent properties in photonics and radiation detection systems. LuI₃ is notable in scintillator and phosphor development due to lutetium's high atomic number, making it relevant for high-energy physics experiments and medical imaging applications where dense, responsive materials are required.
