LAUSANNE
Au and Pt nanoparticle modified SnO2 thin films were prepared by the sol-gel method on glass substrates targeting sensing applications. Structural and morphological properties of these films were studied using Xray Diffraction and Scanning Electron Microscopy. It was proved that the films crystallized in tetragonal rutile SnO2 crystalline structure. Scanning Electron Microscopy observations showed that the metallic clusters' dimensions and geometry depend on the kind of the metal (Au or Pt) while SnO2 films surface remains almost the same: narrostructured granular very smooth. Optical properties of the films were studied using UV-visible spectroscopy. The modified SnO2 films were tested as hydrogen sensors. The response of SnO2, SnO2-Au and SnO2-Pt thin films against hydrogen was investigated at different operating temperatures and for different gas concentrations. The addition of metal nanoparticles was found to decrease the detection limit and the operating temperature (from 180 degrees C to 85 degrees C), while increasing the sensing response signal.
