Vanadium (V) oxide films doped with 10 mol. % NiO and 10 mol. % WO₃ were obtained by aerosol printing. In the first case, the film crystallizes in tetragonal β-V₂O₅ modification with high texturing along the 200 crystallographic plane, while the material is X-ray amorphous when doped with tungsten. The values of electron yield work from the surface of the materials indicate high defectivity of the film containing WO₃. Both samples exhibit anodic electrochromism, however, V₂O₅–10 mol. % NiO shows higher values of optical contrast and coloration efficiency. The results of the study clearly reflect the influence of the nature of the considered dopants on the functional properties of the obtained materials and demonstrate the promising potential of the aerosol printing method for the formation of electrochromic films.
