Se₂S is a mixed chalcogenide ceramic compound combining selenium and sulfur, belonging to the family of chalcogenide materials that exhibit semiconducting and photonic properties. This is primarily a research and specialized material rather than a commodity ceramic; it is investigated for applications requiring optical transparency in the infrared spectrum and potential nonlinear optical behavior. The material represents an emerging area in functional ceramics where composition tuning between different chalcogens enables tailored electronic and optical performance for niche photonic and sensing applications.
