Preparation and Gas Sensing Properties of Nanostructured ZnSnO 3 Thin Films

摘要: Transparent conducting ZnO:SnO2 and perovskite nanostructured ZnSnO3 thin films have been deposited onto preheated glass substrate by a spray pyrolysis technique using water soluble Zinc chloride Stannic as precursors. A fine of the source solution air carrier gas has grown highly textured films. The concentration precursors are kept fixed their ratio were varied as: 50:50 (wt %), 40:60 %) 30:70 respectively. film samples with compositions of: %)were referred S1, S2 S3 Thin S1 found to be composite ZnO:SnO2. ZnSnO3. crystallinity prepared analyzed X-ray diffraction spectroscopy. diffractogram clearly indicated stoichiometric nature band gap energy was observed 4.00, 4.06 4.13 eV We tested sensing performance S3.
