Abstract

The electrochromic phenomena in tungsten trioxide (WO₃) films involve the formation of H_{xWO₃. The maximum value of x in H_xWO₃} is found to be 0.4 from EMF measurements of the WO₃ films during electrochemical reduction. The optical absorbance of H_xWO₃ increases linearly with the increase of x up to x = 0.4. Further injection of catholic charge results in the evolution of hydrogen. Absorbance data also indicate the existence of H_xWO₃ in a single phase.
