CO sensitivity of undoped-ZnO, Cr-ZnO and Cu-ZnO thin films obtained by spray pyrolysis

In this work, we present the gas–sensing properties of chemically sprayed undoped (ZnO), copper–doped (Cu–ZnO), and chromium–doped ZnO thin films (Cr–ZnO), in an atmosphere of carbon monoxide, CO. Films were deposited at 400°C, using zinc acetylacetonate as zinc precursor. Three different atomic con...
