Synthesis of ZnO nanopetals and its application as NO2 gas sensor
Source abstract
Abstract
Abstract In the present work an effort has been made to fabricate nanopetal structured thin film of zinc oxide using chemical route for the efficient and fast detection of NO2 gas at lower operating temperature. The thin film of ZnO was fabricated on the surface of corning glass substrate and Pt inter digital electrodes (IDEs) were grown over the thin film. The as prepared ZnO sensor showed a high sensing response of ~1.19×102 towards 20 ppm of NO2 gas at room temperature with an average response and recovery time of ~1.42 min and 1.71 min, respectively. The obtained results were found reproducible and no ageing effect was observed.
