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 degrees 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 (12s 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. (C) 2014 Elsevier B.V. All rights reserved.
