摘要

Nitridation of TiO_2 films is performed by the simultaneous irradiation of low-energy N_2~+ and H_2~+ ions under substrate-heating condition. Spectroscopic observations of the resultant films clarify the formation of nitrogen-substituted TiO_2 (TiO_(2-x)N_x) with large N fractions and the agglomeration of undesirable oxynitride species attributed to the deep states in the band gap. We find that the addition of a thin TiO_2 cap layer on the ion-irradiated films improves the nitrogen bonding structure and distribution near the surfaces, leading to a good photocatalytic performance even in the visible region.
