Organometallic Approach for the Preparation of Zinc Oxide Nanostructured Gas Sensitive Layers

Abstract:

A reproducible organometallic approach was used in order to prepare zinc oxide gas sensitive layers. Various ZnO nanostructures with well-defined morphology were prepared by controlled hydrolysis of suitable organometallic precursor. These nanomaterials were deposited on miniaturized gas sensors substrates by an ink-jet method. The as prepared devices were tested towards different reducing gases, namely: CO, C₃H₈, and NH₃. We showed that the morphology of these nanostructures significantly influences the sensor response level and selectivity to the reducing gases.
