Materials Properties of Sol Gel Spin Coated Lead Zirconium Titanate Thinfilms

K. Kathiresan, N. Sanakara Subramanian

Abstract: The sol solution is prepared by dissolving appropriate amount of Lead acetate and Zirconium acetylacetonate in a solution containing 2- methoxyethanol, Titanium isopropoxide and acetic acid (Chelating agent), mixed in a stochiometric ratio. This mixed solution has been well stirred, refluxed for one hour at 60 C and allowed for ageing. The as prepared sol solution has been spin coated on to mineral glass substrate under optimized coating conditions. The prepared PZT films have been annealed at 500 C for 2 hours. XRD profile of the PZT thinfilms confirms the formation of poly crystalline pervoskite structure. Optical transmittance of the spin coated pzt thinfilms have been recorded and investigated in the UV- Visible region. FTIR spectrum is absorbed and the results are discussed. Thermal properties of the PZT thinfilms are analyzed from the TGA and DTA measurements and the results have been reported. The surface morphology of the PZT thin films have been recorded and discussed using Atomic Force Microscopic (AFM) technique.
