Sm4 O6

Sm₄O₆ is a mixed-valence samarium oxide semiconductor belonging to the rare-earth oxide family, where samarium exists in both +2 and +3 oxidation states. This compound is primarily of research and developmental interest for optoelectronic and photocatalytic applications, as rare-earth oxides with variable oxidation states can exhibit unique electronic band structures and light-absorption characteristics compared to conventional binary oxides.
