Abstract
In this study, we have investigated the sensing properties of ZnO and Fe-ZnO thin films synthesized by sol-gel spin coating method over transparent conducting glass. The films were subjected to XRD, UV-visible spectroscopy for phase, microstructural and optical properties which confirm the exhaustive evolution of hexagonal wurtzite phase having band gap in UV range. The morphological and topological properties were investigated by SEM and AFM. The sensing properties of ZnO and Fe-ZnO were investigated by using them as an electrode material and recording their resistance in air and in presence of CO gas. Fe-ZnO thin film was found to be more sensitive compared to ZnO thin films having good stability over the days.
