· ErTmO3

ErTmO3 is a rare-earth oxide ceramic compound combining erbium and thulium oxides in a 1:1 stoichiometric ratio. This material belongs to the family of lanthanide oxides and remains primarily in the research and development phase, with potential applications in high-temperature photonics, thermal management, and optical systems. ErTmO3 is of interest to researchers exploring rare-earth ceramics for specialized optical, refractory, and luminescent applications where the combined properties of erbium and thulium oxides may offer advantages over single-dopant alternatives.
