· JVASP-146747· TmAsSe

TmAsSe is a ternary chalcogenide ceramic compound combining thulium, arsenic, and selenium. This material belongs to the family of rare-earth pnictide-chalcogenides, which are primarily investigated for optoelectronic and photonic applications rather than mainstream structural engineering. The compound is of research interest due to its potential as an infrared optical material or semiconductor component, though applications remain largely experimental and confined to specialized photonics laboratories.
