· JVASP-3807· TmIO

TmIO is a layered ceramic oxide compound containing thulium and iodine, belonging to the broader family of rare-earth halide perovskites and mixed-anion ceramics. This material is primarily of research and exploratory interest rather than established industrial production, with potential applications in optical, electronic, and thermal management systems where rare-earth ceramics are leveraged for their unique electromagnetic and structural properties.
