Abstract

The aerosol assisted chemical vapor deposition of monoclinic vanadium pentoxide coatings was performed on fluorine doped tin dioxide coated glass substrates using vanadyl(IV) acetylacetonate at 400 °C for a range of growth periods. It was observed that the sample grown for 1 h presented the best electrochemical response in terms of the highest charge storage (30 mC cm^-2) and the difference in transmittance in the visible and near-infrared spectral regions (27% at 650 nm and 17% at 900 nm) with a fast response time (12 s for coloration and 10 s for bleaching). The importance of achieving samples with (2 0 0) preferred orientation for the improvement of electrochromic performance is highlighted.
