Abstract

In the present work, gasochromic tungsten oxide (WO₃) thin films on glass substrate were fabricated by Pulsed Laser Deposition (PLD) system. Pt was sputtered on the surface of WO₃ thin films as a catalyst layer for hydrogen gas detection. The gasochromic properties of Pt/WO₃ thin films at room temperature were determined by examining their optical transmittance under various H₂-N₂ mixture gas exposures. The results show that in low H₂ atmosphere (0.5%) the room temperature grown Pt/WO₃ thin films still exhibited noticeable transmittance change, within the visible light (550-700 nm) range. WO ₃ thin films have been characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and scanning electron microscopy (SEM). XRD and TEM confirmed that the morphology of the best performance WO₃ thin film is amorphous, and SEM investigations revealed that the thin films were composed of nanotextured grains.
