摘要：

Colored WO3 films were decolorized by the immersion in aqueous solutions containing oxidizing reagents such as Fe-2(SO4)(3) and H2O2. The kinetics of this reaction were examined by solving the diffusion equations using numerical methods. The rate-determining step of the decolorization reaction was found to be a surface reaction, not the diffusion of the color center in the film.
