The response of an RF sputtered NiOx thin film to step potential and its electrochromic mechanism have been investigated. It was found that the NiOx films manifested fine electrochromic properties. Bleaching and coloration did not cause the change of the film's structure. The NiOx films are non-stoichoimetric with Ni vacancies. It is suggested that the bleaching and coloration reaction of the NiOx films in a KOH solution occurs along the grain boundaries. The physical absorption of colored NiOx films is caused by the intraband absorbance of the t2g level of the Ni3+ ion.

Lanthanum-modified lead zirconate titanate (PLZT) thin films, with the La/Zr/Ti ratio being 9/63/37, were deposited on indium tin oxide (ITO)-coated glass substrate by R.F. magnetron sputtering method. Effects of heat-treatment conditions on the structure and chemical homogeneity of the PLZT thin films were investigated by X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The PLZT thin films with desired perovskite structure were obtained after covered with lead oxide and then annealed at 625℃ for 150 min. The binding energy of Pb4f7/2, Ti2p3/2, Zr3d5/2, La3d5/2, and O1s in PLZT thin films were: 138.3, 455.7, 181.2, 835.9, and 529.4 eV, respectively. The excess lead oxide in the PLZT thin films promoted the perovskite structure formation, and baffled the movement of TiO2 and ZrO2 as well. A small quatity of TiO2 and ZrO2 coexisted with PLZT in the surface of samples. And the lack of oxygen inside the films resulted in the valence decrease of a little part of Ti's from +4 to +2.

The effect of annealing on the electrochromic (EC) properties of nickel oxide (NiOx, x>1) films prepared by reactiverf sputtering is studied with electrochemical measurements, optical transmittance analysis, scanning tunneling microscope (STM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). Research results show that EC properties of NiOx films can be changed greatly by annealing. The mechanism for the change of electrochromic properties was discussed in details.

Copper nitride (Cu3N) thin films were prepared on glass substrates by reactive radio-frequency (RF) magnetron sputtering under different nitrogen flow rate. The thermal stability of the Cu3N films was investigated through vacuum annealing treatment at different temperature. X-ray diffraction, scanning electron microscopy and near-normal reflectance spectra were employed to characterize the films. The deposited Cu3N films take on a different preferred orientation, which changed from (111) to (100) with increase of N2 ratio. The grains size of thin films can become small when the N2 ratio increases. The Cu3N phase can completely decompose into Cu and N2 through vacuum annealing treatment at a temperature of 200 1C. The reflectance of as-deposited Cu3N films is quite different from decomposed films.
