Preparation and characterization of ZnO thin films by Sol-gel method on glass substrates

In this work, nanocrystalline ZnO thin films have been created by sol-gel method. The films deposited onto a glass substrate at 50ºC, formed from zinc nitrate, distilled water (pH ≈ 7.0, Conductivity ≈ 36.00µ S/m), Methanol, Ethanol Alcohol, and polyvinyl Alcohol, magnetic stirrer with hot plate. The crystallographic structures of ZnO films and powder were examined utilizing X ray diffraction (XRD). The Scherrer formula was used to calculate the grain size of the films. And Scanning Electron Microscopy (SEM) was utilized to describe structure and morphologies of the saved specimens. The outcome demonstrates that the great film was set up at plunge covering method, the UV-visible spectrum of the sample was obtained using a SL 210 UV-VIS Spectrophotometer-1800, in the wavelength range from 300 to 700 nm. All the tests confirmed the presence of thin film.
