| Abstract: | The porous titanium dioxide film with nano crystalline was prepared by anodic oxidation of titanium, the different amount of Fe 3 in the film had been taken by adding the ferric ion into the electrolyte during anodic oxidation. The effect of different amount of Fe 3 dopant on the absorption spectra and the photo catalytic activity of the film was studied, it was showed that the Fe 3 dopant caused the red movement of the absorption edge for the incoming light. The mechanism was discussed. |
