Architectural control of nanostructured ZrO2thin films via the electrostatic spray deposition technique using zirconatrane as a precursor

Year: 2010

Type: article

Abstract: Nanostructures of zirconium dioxide (ZrO 2 ) thin films with different morphologies were deposited on a glass substrate via electrostatic spray deposition, using zirconatrane as a precursor. Structure formation can easily be controlled by tuning the weight ratio of zirconatrane to ethanol without the addition of a stabilizer to the reaction mixture. The ZrO 2 structures presented nanoflower- and nanoneedle-like morphologies. Furthermore, the humidity-sensing properties of those sensors based on these thin films were evaluated. Compared with the needle-like sensor, the flower-like ZrO 2 sensor has better sensitivity, higher reproducibility and quicker recovery behavior to humidity over a wide range of relative humidity (RH) (0–100% RH).
