· TmBiO3

TmBiO3 is a rare-earth bismuth oxide ceramic compound combining thulium (a lanthanide element) with bismuth oxide in a perovskite-related crystal structure. This material belongs to the family of mixed-metal oxides and remains primarily in the research and development phase, with potential applications in photocatalysis, optical devices, and high-temperature dielectric systems where the rare-earth incorporation offers tunable electronic and optical properties.
