HYDROGEN GAS SENSORS BASED ON ZnO THIN FILMS
International Journal of Semiconductor Science & Technology (IJSST)
Nanocrystalline (ZnO) thin films were synthesized by chemical spray pyrolysis technique, a 0.1 M Spray solution is prepared by dissolving Zinc Chloride (ZnCL 2) in 100 ml distilled water were deposited on glass substrates heated 450. The crystal structure and morphology of synthesized films were characterized by X-ray diffraction (XRD) and Atomic Force Microscope (AFM). The crystallite size was evaluated to be 48.599 nm by using Scherrer's equation and the optical absorption spectra were takenfatcat:nrug6i5xbrb2rmlmqxvb563ghi
