TmGaO3 is a rare-earth gallate ceramic compound combining thulium oxide with gallium oxide in a perovskite-related crystal structure. This material is primarily of research and developmental interest rather than established industrial production, investigated for its potential in optoelectronic and high-temperature applications where rare-earth dopants and wide-bandgap semiconductors are advantageous.
