Tin oxide films were deposited on cylindrical alumina substrates using dip coating technique. These films were subsequently dried and sintered at 500 degrees C for development of microstructure having nanoparticles of SnO2 and adhesion with the substrate. These resistive gas sensors were tested for H-2 of concentration range 7-3900 ppm at the operating temperature of 260 degrees C. The sensors also showed good response to acetone vapour (11-5500 ppm) at operating temperature of 200 degrees C. These sensors showed good temperature sensor selectivity. The structural and microstracural analyses of the films were carried out using X-ray diffractometry, scanning electron microscopy (SEM) and atomic force microscopy (AFM).
