Abstract
Crystal structure, morphology, and electrochromic properties of V2O5 film prepared using vanadyl alkoxoacetylacetonate as precursor have been studied. We have shown that the obtained vanadium pentoxide contains significant amount of V4+ cations, which is indicated by low electron work function. This results in material possessing anodic electrochromism (coloring upon oxidation) with rapid bleaching process (1 s upon the corresponding potential application). Anodic coloration is observed in the whole visible light spectrum, as well as in near IR region up to 1100 nm. The obtained data show high prospects for approach to formation of V2O5-based films using vanadyl acetylacetonate as precursor and application of these films as components of smart windows and displays, optical properties of which could be controlled by electrical current application.
