Sm4 As8 O18
semiconductor· Sm4 As8 O18
Sm₄As₈O₁₈ is a rare-earth arsenate semiconductor compound combining samarium, arsenic, and oxygen in a mixed-valence oxide structure. This material belongs to the family of rare-earth oxides and arsenates, which are primarily of research interest for their unique electronic and optical properties rather than established industrial production. The compound is investigated in materials science laboratories for potential applications in optoelectronics, photocatalysis, and solid-state device research, where the rare-earth element provides luminescent or catalytic functionality, though it remains largely in the experimental/developmental stage without widespread commercial deployment.
