change was observed for N+ implanted TiO2. Raman spectra prove the formation of TiNx and oxygen vacancies in the implanted … TiO2, which is considered as the origin of absorption edge shifting. The work may give a hint to increase the … photocatalytic activity of TiO2 in the visible region at the molecule level. …
