摘要: Abstract The characteristics of the electrochromic process sputtered hydrated nickel oxide films have been investigated by cyclic voltainmetry, in situ optical transmittance and ac impedance spectroscopy. results indicate that state coloration these is related to conditions used drive process, whose kinetics at high positive potentials become controlled ion diffusion into from structure.
