Pr2 Se1 O2
semiconductor· Pr2 Se1 O2
Pr₂SeO₂ is a rare-earth oxyselenide semiconductor compound combining praseodymium with selenium and oxygen, representing an emerging class of layered mixed-anion materials. This is primarily a research compound studied for its electronic and optical properties within the broader family of rare-earth chalcogenides and oxychalcogenides. Such materials are being investigated for potential applications in optoelectronics, thermoelectrics, and photovoltaics, where the combination of rare-earth elements with mixed anionic frameworks can enable tunable bandgaps and enhanced carrier transport compared to conventional binary semiconductors.
