In the present work, three transition metal oxides; tungsten trioxide (WO3), zirconium dioxide (ZrO2) and nickel oxide (NiO) were prepared as thin films. Spray pyrolysis and magnetron sputtering techniques were employed to deposit these thin films on indium-doped tin oxide (ITO) coated glass substrates. The prepared samples were characterized by x-ray diffraction, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and UV-visible spectroscopy. The smart window (device) with the configuration: glass/ITO/WO3/ZrO2/NiO/ITO/glass was fabricated and characterized by UV-visible spectroscopy. This device was tested by applying ±5V and high optical transmittance modulation at about 30.93% was observed.
