The concept is demonstrated by tungsten trioxide inverse opal structure as optical transducer material for hydrogen sensing. The sensing behavior is analyzed in a temperature range from room temperature to 500 °C and in a wide hydrogen concentration range (3000 ppm to 10%). The sensing mechanism is mainly the refractive index The refractive index of tungsten oxide thin film was found to increase with sputtering power but decreased with wavelength as shown in figure 4.

2020-09-02 · A bandgap of 3.26 eV and a refractive index of 2.36 were obtained, consistent with the previous reports for WO 3 films. The pinhole-free films were found to be a mixture of hexagonal and monoclinic WO 3 , with an increasing monoclinic nature after annealing.

2009-09-02 · Variation of (a) refractive index and (b) extinction coefficient with wavelength for tungsten oxide films deposited in ambient nitrogen of 12 Pa at different substrate temperatures. Download figure: Standard Export PowerPoint slide Tungsten oxide films (WO3) are deposited by thermal evaporation techniques using the starting materials of tungsten (W) and tungsten oxide (WO3). By varying deposition parameters, three main types of WO3 film exhibiting different optical properties form. These are blue, gray, and colorless films.

Tungsten oxide films were prepared by a complexing agent-assisted sol-gel process. All the films were at 500°C were crystalline and transparent. The refractive index n and extinction coefficient k of the films were calculated from the transmittance and reflectance spectra in the visible and infrared regions.
