Abstract

The photoabsorption edge shifting from UV to visible region accompanied with increased intensity and Raman features change was observed forN+implantedTiO2. Raman spectra prove the formation ofTiNxand oxygen vacancies in the implantedTiO2, which is considered as the origin of absorption edge shifting. The work may give a hint to increase the photocatalytic activity ofTiO2in the visible region at the molecule level.
