Title

STUDY OF BAND GAP ENERGY AND REFRACTIVE INDEX OF SUPERCONDUCTING CERAMIC GdBa2Ca3Cu4O10.5

Abstract

ABSTRACT Superconducting ceramic GdBa2Ca3Cu4O10.5 is a perovskite with orthorhombic crystal system in nanometer range. To prepare the ceramic we followed conventional steps of solid state reaction route using a special furnace. The ceramic is calcined at 30, 500, 850 and 900 degree Celsius. After each calcination UV-VIS analysis is done. Absorbance and reflectance spectra at different wavelengths are obtained. Optical band gaps at different temperatures are determined with the help of Tauc plots. Effect of temperature and particle size on band gap energy is studied. Band gaps are tunable with respect to temperature. Refractive index of the ceramic is calculated and its variations with different parameters such as wavelength and photon energy are noted. Dispersion of refractive index is studied using Wemple- Di Domenico single-oscillator model. Band gap energy, oscillator energy and dispersion energy of refractive index at different temperatures are calculated. They are found to be decreasing with increasing temperature.
