摘要
Thin films of TiO2 and TiO2-V2O5 were obtained by dip-coating sol-gel technique. Sols were prepared from titanium ethoxide and inorganic V2O5 sol received by dissolution of vanadium pentoxide in hydrogen peroxide. Sol-gel TiO2 and TiO2-V2O5 films are deposited on conductive glass substrates. TiO2 and TiO2-V2O5 systems were characterized by FTIR and Raman spectroscopy. Optical transmittance measurements were carried out. Electrochromic characterization was recorded by cyclic voltammetry using three-electrode arrangement. All samples demonstrated electrochromic effect. (c) 2005 Elsevier Ltd. All rights reserved.
