Abstract

Nanostructured TiO2–SnO2 films were prepared by a facile aqueous sol–gel route. The prepared sols showed particle size in nano-meter scale. X-ray diffraction (XRD) analysis revealed that phase composition of the films depend on Sn:Ti molar ratio and annealing temperature. Moreover, SnO2 retarded the anatase to rutile transformation. Transmission electron microscope (TEM) image showed that one of the smallest crystallite sizes was obtained for TiO2- SnO2 binary mixed oxide, being 3 nm. Field emission scanning electron microscope (FE-SEM) analysis revealed that the deposited films had nanostructured morphology with the average grain size in the range 20-40 nm. Thin films produced under optimized conditions showed excellent microstructural properties for gas sensing applications towards low concentrations of CO gas at low operating temperature of 200oC.
