· Y2 Se1 O2

Y2Se1O2 is an experimental mixed anionic semiconductor compound combining yttrium, selenium, and oxygen in a layered or complex crystal structure. This material belongs to the family of rare-earth oxyselenides, which are being investigated for optoelectronic and photovoltaic applications due to their tunable bandgap and potential for efficient light absorption. While not yet commercially established, oxyselenide semiconductors are of research interest as alternatives to conventional oxides and chalcogenides in next-generation photocatalytic devices and thin-film electronics where the mixing of anionic species can provide enhanced electronic properties.
