Eu2CaO3

Eu₂CaO₃ is a rare-earth oxide ceramic compound containing europium and calcium, belonging to the class of lanthanide-based oxides. This material is primarily investigated in research contexts for photoluminescent and optical applications, where europium's characteristic red emission under UV or cathode-ray excitation is leveraged. The compound represents a member of the rare-earth oxide family with potential use in display technologies, radiation detection, and high-temperature ceramics, though it remains largely experimental rather than a widely deployed engineering material.
