The tungsten oxides were observed by SEM and showed as expected smooth surfaces with no cracks because of the low oxidation temperature. XRD shows a monoclinic (m-WO 3) or orthorhombic (o-WO 3) nanocrystal-line structure. The lattice parameters of m-WO 3 and o-WO 3 species (hydrogen) into the tungsten oxide lattice. Surface reactions of tungsten oxide with other gases have a much lower effect on the refractive index and the photonic band gap, respectively. Conclusion The shown hydrogen sensor based on tungsten oxide inverse opals can be used to detect hydrogen from 3000 ppm to 10 % up to 500 °C. Molecular Formula.

2000-11-01 Electrical and optical properties of reactively sputtered tungsten oxide films have been investigated in relation to the oxygen concentration in sputtering atmosphere. The films with 5200–6600 Å thick were prepared under a constant pressure of 5×10 −3 Torr using a mixture of Ar and 4–50% O 2. Electrical resistivity and spectral transmittance of the films formed depend extremely on the Tungsten (VI) oxide, also known as tungsten trioxide or tungstic anhydride, WO 3, is a chemical compound containing oxygen and the transition metal tungsten. It is obtained as an intermediate in the recovery of tungsten from its minerals.
