Abstract
CeO2 nanoparticles (NPs) gas sensor was fabricated on glass substrate by using spin coating technique. The developed CeO2 NPs thin films influence the gas sensing performance towards NO2 gas in the range of 5-200 ppm. For 100 ppm of NO2, the response of NPs thin film is 44%. The morphology of CeO2 NPs thin film exhibited high sensitivity, good selectivity and excellent repeatability for 100 ppm level of NO2 gas at 200oC operating temperature. The gas-sensing measurements demonstrate that the CeO2 NPs sensing material is an excellent candidate for NO2. The CeO2 NPs thin films were characterized for their structural and chemical properties using XRD, SEM and FTIR spectroscopy.
