Abstract

The electrochromism of $WO_3$ and $V_2O_5$ thin films have been studied. The $WO_3$ thin film is found to be cathodic coloration material and the coloration efficiency of this film is close to $60 [cm^2/C]$ in the near infrared region. The $V_2O_5$ thin film exhibits cathodic coloration in tile near infrared and anodic coloration in the blue and near UV region. The cathodic coloration in the $450{\sim}1100 nm$ wavelength range is relatively weak with a maximum coloration efficiency of $6 [cm^2/C]$).
