Ce2 S1 O2
semiconductor· Ce2 S1 O2
Ce₂SO₂ is a mixed cerium oxide-sulfide semiconductor compound belonging to the rare-earth chalcogenide family. This material is primarily of research interest for optoelectronic and photocatalytic applications, where the combination of cerium's variable oxidation states and sulfide chemistry offers tunable band gap characteristics and enhanced light absorption compared to conventional oxide semiconductors. While not yet widely commercialized, cerium-based semiconductors show promise in next-generation photovoltaic devices, environmental remediation, and visible-light photocatalysis where their chemical versatility and rare-earth properties provide advantages over traditional metal oxides or simple sulfides.
