· Sr3 Cr2 S2 O5

Sr₃Cr₂S₂O₅ is an oxysulfide semiconductor compound combining strontium, chromium, sulfur, and oxygen in a mixed-anion crystal structure. This is a research-phase material within the broader class of chalcogenide and oxychalcogenide semiconductors, studied for its potential to bridge properties of oxide and sulfide systems. Industrial applications remain exploratory, with primary interest in photocatalysis, solar energy conversion, and electronic device research where mixed-anion semiconductors offer tunable band gaps and enhanced light absorption compared to conventional oxide or sulfide alternatives.
