Abstract

The photoabsorption edge shifting from UV to visible region accompanied with increased intensity and Raman features change was observed for N ⁺ implanted TiO ₂. Raman spectra prove the formation of TiN _x and oxygen vacancies in the implanted TiO ₂, which is considered as the origin of absorption edge shifting. The work may give a hint to increase the photocatalytic activity of TiO ₂ in the visible region at the molecule level.
