The electrochromic property of MoO3/WO3 nanocomposite films

Electrochromic films of molybdenum / tungsten trioxide (MoO3/WO3) prepared from a solution of peroxotungstic acid (PTA) were formed on indium doped tin oxide (ITO) glass substrate using the sol-gel and dip coating methods at difference ratios of MoO3 of 15, 30 and 50 %mol. The effect of MoO3 on the...

Description
Summary:Electrochromic films of molybdenum / tungsten trioxide (MoO3/WO3) prepared from a solution of peroxotungstic acid (PTA) were formed on indium doped tin oxide (ITO) glass substrate using the sol-gel and dip coating methods at difference ratios of MoO3 of 15, 30 and 50 %mol. The effect of MoO3 on the structure, morphology, optical and electrochromic properties of films were investigated by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Atomic force microscope (AFM), Scanning electron microscope (SEM), UV-vis spectrophotometer and Cyclic voltammogram (CV), respectively. The 30 %mol MoO3 doped WO3 film demonstrated a good electrochemical properties in terms of diffusion coefficient better than other ratios and pure WO3 due to its large surface area of the high roughness composite film.
