· JVASP-49146· SmEr3S6

SmEr3S6 is a rare-earth sulfide ceramic compound combining samarium and erbium in a sulfide matrix, belonging to the family of lanthanide chalcogenides. This material is primarily of research and developmental interest rather than established industrial production, with potential applications in thermal management, luminescent devices, and advanced ceramics where rare-earth properties are leveraged for specialized optical or electronic functions.
