Abstract

NicNickel oxide (Ni0) thin films deposited by electron-beam evaporation were studied using Fourier Transform Infrared Spectroscopy(FTIR), Rutherford Backscattering Spectroscopy (RBS), and spectrophotometry. Evaporated nickel oxide films ehibited good electrochromic behavior and a coloring efficiency of 30.1 cm²/C coating was 4.41 g/cc and stoichiometry was Nio_1.4; both established by RBS. The infrared spectral properties of the as-deposited film was consistent with the structure being Ni0_x. After repetitive electrochromic cycling in 1N KOH, the film changed to a structure more similiar to the hydrated nickel hydoxide films previously reported in the literature.
