· Er4 V4 O14

Er₄V₄O₁₄ is a mixed rare-earth vanadium oxide ceramic compound combining erbium (a lanthanide) with vanadium in a complex oxide structure. This material belongs to the family of rare-earth vanadates, which are primarily explored in research contexts for their potential in optical, electronic, and thermal applications due to the unique properties imparted by erbium's f-electron configuration and vanadium's variable oxidation states.
