· Cs2Se

Cs₂Se is an inorganic ceramic compound composed of cesium and selenium, belonging to the family of alkali metal chalcogenides. This material is primarily investigated in research contexts for optoelectronic and photonic applications due to its wide bandgap and potential for UV-to-visible light conversion, though it remains largely experimental and not widely commercialized in mainstream engineering.
