Er2 Se1 O2
semiconductor· Er2 Se1 O2
Er₂Se₁O₂ is an erbium-based mixed anionic semiconductor compound combining rare-earth, chalcogenide, and oxide chemistry. This is a research-phase material primarily studied for optoelectronic and photonic applications, where the erbium dopant enables near-infrared emission relevant to telecommunications wavelengths. The layered oxychalcogenide structure offers potential for tunable band gaps and enhanced light-matter interactions compared to single-anion semiconductors, making it of interest in integrated photonics and quantum optics research communities.
