SrTi0.6Fe0.4O3−δ (STF40) gas sensors were deposited using a novel modified sol–gel route. The influences of thermal annealing (400–750 °C) on the crystallization and oxygen sensing performance were investigated. As revealed by XRD, TEM and XPS studies, the deposited sol–gel thin films had amorphous...
