Niobium oxide films are promising cathodic electrochromic materials that in certain aspects can compete with the more frequently studied WO{sub 3} films. The films reported here were prepared using the sol-gel route from a NbCl{sub 5} precursor. The electrochromic properties were pronounced for crystalline films heat-treated at 500 C exhibiting transmittance changes between the colored and bleached states of 60% in the ultraviolet (UV) and 80% in the visible and near-infrared spectral regions. The reversibility of electrochromic changes of thick niobium oxide films (d > 250 nm) was enhanced by lithiation.
