Analysis of Bandgap Energy and Refractive Index of Ferroelectric Perovskite Pbbatio3
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
Lead barium titanate (PbBaTiO3) is a newly designed ferroelectric, nanocrystalline ceramic with perovskite structure prepared by solid state reaction method. Inorder to study the band gap energy, refractive index and other optical properties of this ceramic, UV-VIS analysis is done at different annealing temperatures. Absorbance and reflectance spectra are obtained from analysis. Band gap energy at different temperatures is determined using Tauc plots and is found to be decreasing with temperature. Absorption edge is studied in terms of Urbach energy. Refractive index is calculated and their variations with wavelength and photon energy are noted. Dispersion of refractive index is studied and band gap energy, oscillator energy and dispersion energy is calculated using Wemple- Di Domenico single-oscillator model.
