Abstract
Tungsten oxide thin films were prepared using gas impulse magnetron sputtering and as-deposited samples were additionally annealed at 400°C to obtain nanocrystalline structure. Surface studies re-vealed good homogeneity of the prepared coatings. Thin films were exposed to hydrogen with different concentrations and their optical response, that is the decrease of transmission coefficient, was meas-ured in the spectral range from 200 to 10⁰⁰ nm. The change of resistance upon exposure to hydrogen,was also measured to compare optical and electrical reponse.
