· LuAlO3

Lutetium aluminate (LuAlO₃) is a rare-earth ceramic compound combining lutetium oxide with aluminum oxide, valued for its high refractive index and optical transparency in the infrared spectrum. It is used primarily in photonic and optoelectronic applications, including laser hosts, scintillator materials for radiation detection, and substrate materials for thin-film devices requiring lattice matching with functional oxides. Engineers select LuAlO₃ when demanding applications require the combination of chemical stability, thermal shock resistance, and optical performance that conventional alumina or other perovskite oxides cannot provide, though its cost and specialization limit it to research and high-performance industrial contexts.
