· Eu(ErSe2)2

Eu(ErSe2)2 is a rare-earth selenide compound belonging to the family of lanthanide chalcogenides, specifically a europium erbium diselenide phase. This material is primarily of research and development interest rather than established industrial production, studied for potential applications in optoelectronic and photonic devices that exploit the unique electronic properties of rare-earth elements combined with selenide semiconductors.
