Abstract

Abstract: The last few years have seen an upsurge in attention towards the investigation and application aspect of the electro-optic properties of ferroelectric materials. The current work reports the effect of substrates on the optical characteristics of the lead zirconate titanate (PZT) thin films fabricated via the novel sol–gel route. The PZT thin films were deposited on to three different substrates i.e. corning glass, ITO glass, and Quartz by spin-coating technique. The thin film samples were tested for their structural and optical properties via XRD, Raman, and UV–Vis spectroscopy. The XRD patterns revealed formation of perovskite crystal structure when the samples were calcined at 650 °C for 2 h. The optical energy band gap values for the thin film samples varied with the substrates and were reported to be 3.55 eV for corning glass, 3.59 eV for ITO glass and 3.79 eV for Quartz.
