Recently, the tungsten oxide (WO3) nanoplate were grown by acid treatment process on transparent conductive oxide coating film shows promising application for electrochromic devices which was low temperature process, cost-effective and applicable for large area devices. However, their poor adhesive property lead stability. However, the improvement of the electrochromic (EC) devices can be prepared by depositing an ultra-thin WO3 adhesive layer before the grown of WO3 nanoplate. In this experiment, the WO3 nanoplates were grown on indium doped tin oxide (ITO)-coated glass substrate using nitric acid, and annealing treatment at 300 C for 2 hour. The ultra-thin WO3 film adhesive layers were deposited by DC reactive magnetron sputtering at different film thicknesses (5-40 nm). The effect of the ultra-thin film WO3 adhesive layer on the morphology, optical and EC properties was investigated by X-ray diffraction and field emission scanning electron microscope. The EC properties of nanostructure WO3 in H2SO4 electrolyte were analyzed by UV-Vis-NIR spectrophotometer. The result indicated that the ultra-thin WO3 film adhesive layer show better improving the cycling stability with high optical contrast.
