Strontium selenide (SrSe) is an inorganic ceramic compound belonging to the alkaline-earth chalcogenide family, characterized by ionic bonding between Sr²⁺ cations and Se²⁻ anions in a rock-salt crystal structure. While primarily a research material rather than a commodity ceramic, SrSe and related strontium chalcogenides have been investigated for optoelectronic and photonic applications due to their wide bandgap and potential for infrared transparency. The material remains largely experimental but represents a class of wide-bandgap semiconductors and scintillator materials relevant to specialized optical, radiation detection, and thin-film device research, where it competes with more established alternatives like SrTe and CaWO₄.
