Abstract

Vanadium(V) oxide films doped with 10 mol % NiO and 10 mol % WO3 were prepared by aerosol printing. In the case of nickel doping, the film crystallized in the tetragonal β-V2O5 modification with strong texturing along the {200} crystallographic plane, while tungsten doping resulted in an X-ray amorphous material. The nickel-doped film consisted of one-dimensional structures, whereas the V2O5–10 mol % WO3 composition formed particles of irregular or nearly spherical shape. The electron work function values indicated high number of defects in the WO3-containing film. Both samples exhibited anodic electrochromism, with the V2O5–10 mol % NiO demonstrating higher optical contrast and coloration efficiency. The results clearly show the influence of dopant nature on the functional properties of the obtained materials and demonstrate the potential of aerosol printing for fabricating electrochromic films.
