Structural and Optical Properties of Zn2SnO4 Thin Films prepared by Spray Pyrolysis


Zn¬¬2SnO4 thin films were prepared using spray pyrolysis technique over cleaned glass substrate with zinc chloride and tin (IV) chloride as precursors. The preparative parameters such as substrate temperature, solution concentration, distance from spray-nozzle to substrate, pressure of carrier air, etc., were optimized to obtain large area, uniform, thin films. The substrate temperature during deposition is varied between 350oC to 500oC to study the influence of temperature over the structural properties of Zinc Stannate (Zn2SnO4) thin films. The structural analysis of Zn2SnO4 thin films were carried out using X-ray Diffraction (XRD) technique and it is observed that the films are highly crystalline. Various diffraction peaks of Zn2SnO4 powder where observed in the XRD pattern. The surface morphology of the films where studied by using Scanning Electron Microscope (SEM). The EDAX analysis shows the percentage of doping. Optical transmittance measurements indicate that the Zn2SnO4 films have a direct band gap of the films varies from 3.1 to 3.4 eV which is then confirm the formation of well-crystallized Zn2SnO4 films. PL spectra in the green region, which means Zn2SnO4 film, may have application as green light emitter.
