SnO2 gas sensors were irradiated by 1.75 MeV electron beams and effects of the EB irradiation on the performance of the sensors were studied.The results showed that sensitivity of the irradiated SnO2 sensors to hydrogen and ethanol were greatly improved.The sensitivity and coefficient of selectivity to hydrogen and ethanol were enhanced with increasing doses
whereas the response and recovery time decreased.Mechanism of the sensitivity improvement of the irradiated SnO2 sensors was discussed with the adsorption theory on surface.
