摘要：

Tin-doped cadmium oxide nanostructures were synthesized by a cost effective and energy efficient microwave-assisted wet chemical technique. The effect of doping concentration of Sn from 1 to 5 wt% on the morphological and micro structural properties of CdO nanoparticles was investigated. Characterization measurements have revealed that Sn ions successfully incorporate within the face centered cubic crystalline structure of CdO. The electrical and CO2 sensing properties of the synthesized Sn-doped CdO nanostructures were tested at different operating temperatures. It was confirmed that Sn doping in CdO promotes the CO2 sensing properties in terms of higher response and lower response/recovery time compared to undoped CdO nanostructures.
