Sm2AsSe

Sm₂AsSe is a rare-earth chalcogenide ceramic compound combining samarium with arsenic and selenium. This material belongs to the family of lanthanide pnictide-chalcogenides, which are primarily of research interest for their potential optoelectronic and thermoelectric properties. While not yet established in mainstream industrial applications, materials in this class are being explored for mid-infrared photonics, solid-state radiation detection, and next-generation thermoelectric devices where the combination of rare-earth elements and mixed anionic chemistry can yield tunable band structures.
