· JVASP-30472· LuIO

LuIO is a lutetium iodate ceramic compound with a layered crystal structure, belonging to the rare-earth oxide family of functional ceramics. This material is primarily investigated in research contexts for applications requiring high density and layered crystal chemistry, with potential use in optical, electronic, or structural applications where rare-earth ceramics provide unique properties unavailable in conventional materials. Its notably low exfoliation energy suggests potential for thin-film or nanosheet synthesis, making it of interest to researchers exploring two-dimensional ceramic materials and advanced functional composites.
