Tm4 Sb4 O14

Tm₄Sb₄O₁₄ is a rare-earth antimonate ceramic compound combining thulium (a lanthanide) with antimony oxide in a mixed-valence structure. This material belongs to the family of complex rare-earth oxides and remains largely in the research phase, with interest driven by its potential semiconducting properties and crystal chemistry relevant to photonic and electronic applications. As an experimental compound, Tm₄Sb₄O₁₄ is studied primarily in academic and advanced materials laboratories to understand rare-earth doping strategies, defect engineering, and phase stability in ternary oxide systems that could enable next-generation optical or thermal management devices.
