The origin of visible light absorption in chalcogen element (S, Se, and Te)-doped anatase TiO2 photocatalysts

We use first-principles calculations to clarify the origin of the visible light absorption in chalcogen element-doped TiO2. Our results show that interstitial doping is not the origin of visible light absorption under any equilibrium growth conditions, but rather, sensitization is achievable via sub...
