| Abstract: | TiO_2 nanoparticulate films were prepared by means of Plasma-enhanced Chemical Vapor Deposition (PECVD). By further surface treatment by TiCl_4 or O_2 plasma, films with dif- ferent surface properties were obtained. It was found that treatment by TiCl4 plasma enhanced the amount of Ti3 suiface state and Ti dislocation of the film, detected by the surface photovoltage spectroscopy, while O_2 plasma surface treating enhanced its amount of O_2 surface state. It was also indicated by the H_2O adsorption experiment that film treated by O_2 plasma had larger separation efficiency for photogenerated carriers than the one treated by TiCl_4 plasma. |
