Chemical sensors based on Surface Plasmon Resonance (SPR) measurements have been proposed in various applications ranging from biomedical and environmental monitoring to industrial process control. In this work, preliminary surface-plasmon-resonance studies have been used to characterise the response in presence of different gas and vapours of thin TiO2 porous films containing different types of phthalocyanine. The films were prepared using sol-gel technique. Low temperature annealing of the films (80 degrees C) ensured the formation of microporous TiO2 backbone and the preservation of phthalocyanine.

Abstract
Chemical sensors based on Surface Plasmon Resonance (SPR) measurements have been proposed in various applications ranging from biomedical and environmental monitoring to industrial process control. In this work, preliminary surface-plasmon-resonance studies have been used to characterise the response in presence of different gas and vapours of thin TiO2 porous films containing different types of phthalocyanine. The films were prepared using sol-gel technique. Low temperature annealing of the films (80 degrees C) ensured the formation of microporous TiO2 backbone and the preservation of phthalocyanine.File in questo prodotto:
