Y1 Sc1 O2

Y₁Sc₁O₂ is a rare-earth oxide semiconductor compound combining yttrium and scandium in a mixed-valence or defect-fluorite crystal structure. This material is primarily of research interest for advanced optoelectronic and photonic applications, where its bandgap and optical properties can be engineered through rare-earth doping and defect management. The compound represents an emerging alternative in the rare-earth oxide family for next-generation wide-bandgap semiconductor devices and scintillator materials where conventional oxides like Y₂O₃ or ScOₓ show limitations.
