    Abstract

    SnO2 nanowires were synthesized via vapor transport method by modulating the thickness of the Gold (Au) catalyst. The effect of morphology and photoluminescence properties of nanowires on gas sensing was investigated. The structural and morphological studies reveal that the synthesized nanowires are crystalline in nature with high density. The nanowires were evenly spread on the surface of the substrate. These nanowires were tested for gas sensing properties based on change in resistance under exposure to air and gases (CO, CH4, Methanol). The results showed an improved response as compared to the previous studied. These sensors have potential applications in advanced sensing devices.
