Abstract
A new method of formation of electrochromic MoO3 thin oxide film on electric conducting glass (ITO glass) has been investigated for use in place of the conventional vacuum evaporation method. The ITO glass was cathodically electrolyzed in an aqueous solution of 0.007 mol/l lithium molybdate at a constant current density of ca. 3 A/m2 at 25°C. Blue, conductive and adhesive oxide film was obtained. Cycles of the coloration and bleach were repeated in the propylene carbonate solution of lithium perchlorate. A good reversibility was obtained.
