Abstract:Sensing response of synthesized composite oxide of zinc and tin to ethanol vapor before and after irradiation has been reported in this paper. Composite oxide powder has been synthesized by a chemical route followed by calcination. Beginning with the 0.1 M solutions of zinc chloride and stannic chloride in distilled water, ammonia solution was added slowly with continuous stirring for half an hour to obtain precipitates. The synthesized precipitates were filtered, dried at ~ 120oC and divided into three portions and each portion was calcined for three hours at different temperatures of 400, 600 and 800oC respectively. For structural and morphological characterization, these powders were exposed to XRD and TEM analysis. To construct sensors, water based thick films of these powders were deposited on the alumina substrates having pre-deposited gold electrodes. Irradiation of fabricated sensors was carried out with 100 MeV O7+ ions at fluences of 1x1011, 1x1012 and 1x1013 ions/cm2 using UD15 Pelletron tandem accelerator. The sensing response of these sensors at different temperatures to ethanol vapor was examined before and after irradiation. The results disclosed that sensing response remained same before and after irradiation signifying that Zn-Sn composite oxide is a radiation hard material.
