· JVASP-35738· CaZnSe2

CaZnSe₂ is a ternary II-VI semiconductor ceramic compound combining calcium, zinc, and selenium elements. This material belongs to the chalcogenide ceramic family and is primarily of research and developmental interest rather than established industrial production. The compound is investigated for optoelectronic and photonic applications where its semiconductor bandgap and crystal structure offer potential advantages in infrared detection, scintillation, or solid-state lighting contexts, though it remains largely in the laboratory phase compared to more mature binary alternatives like ZnSe.
