摘要：
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. For structural and morphological characterization, these powders were exposed to XRD and TEM analysis. To construct sensors,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 1 x 10(11), 1 x 10(12) and 1 x 10(13) ions/cm(2) using UD15 Pelletron tandem accelerator at Inter University Accelerator Centre, New Delhi. 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.
