Chemistry, Physics and Technology of Surface| Резюме: | Nanostructured hydrated WO3 films deposited on glass and on glass with a layer of SnO2 or with Au film have been obtained by chemical and electrochemical methods. The angular and spectral dependences of total internal reflection and surface plasmon resonance for different values of oxide potential have been measured on fabricated planar glass-WO3 and glass-Au-WO3 structures placed in an electrolyte (0,5M H2SO4). These dependences were compared with the results of computer simulation, using experimental values of n and k for these WO3 films, prepared by interferometry. It has been shown that in presence of thin catalyst layer (Pt or Pd) on WO3 surface optical hydrogen sensors for the determination of hydrogen content in air at 0-5 vol.% H2 can be created based on these structures. |
