A new method for deposition nitrogen‐doped TiO 2 nanofibers films was proposed. By using atmospheric pressure plasma jet generated by dual‐frequency power sources, the morphologies of these TiO 2 films were investigated by scanning electron microscopy. The structures of these films were characterized by X‐ray diffraction and Raman Shift Spectroscopy. The elemental composition of these films [Colour figure can be viewed at wileyonlinelibrary.com ] were characterized by means of X‐ray photoelectron spectroscopy. The optical absorption of these films were studied by UV‐vis absorbance spectra. These results indicated that the nitrogen‐doped nanofibers TiO 2 films have mixed phases of anatase and rutile. They also display narrow band gap. The I‐V characteristics curves exhibited good conductivity ability. Optical emission spectroscopy (OES) was measured to analyze the active group.
