Sr2 S1 O1

Strontium oxysulfide (Sr₂SO) is an inorganic semiconductor compound combining strontium, sulfur, and oxygen in a mixed-valence structure. This material belongs to the rare-earth and alkaline-earth chalcogenide semiconductor family, primarily investigated for optoelectronic and photonic applications where its electronic band gap and crystal structure offer tunable optical properties. Industrial interest centers on thin-film deposition for photovoltaic devices, phosphor technologies, and emerging quantum materials research, where its stability and semiconductor behavior present advantages over purely sulfide or purely oxide analogs in specific device architectures.
