Spray Pyrolysis Technique for the deposition of Lead Oxide (PbO)Thin Films; its Electrochemical behaviour and Structural and optical Properties

摘要

Thin film of Lead oxide (PbO)was prepared by spray pyrolys is technique on glass substrate at 250℃. The cyclic voltammetry measurement was carried out to study the oxidation reduction reactions of non-aqueous lead ions at various molar concentrations which is from 0.01 M to 0.09M. Elecrochemical studies were carried out with Ag/AgCI as a reference electrode, Pt as working electrode while platinum mesh as counter electrode. Lead oxide appears to be poisonous yellow or reddish yellow solid. Structural characterization of films was analyze with X- ray diffraction (XRD) and optical band gap was determined by UV-Vis Spectroscopy.
