STUDY ON THE MECHANISM OF VISIBLE ABSORPTION ENHANCEMENT FOR N+ IMPLANTED TiO2 BY RAMAN SPECTROSCOPY

The photoabsorption edge shifting from UV to visible region accompanied with increased intensity and Raman features 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.
