Abstract
In this project titled “INVESTIGATIONS OF STRUCTURAL AND OPTICAL PROPERTIES ON Pr0.7Sr0.3MnO3/ Gd0.7Sr0.3MnO3/ Dy0.7Sr0.3MnO3 ” I have studied the structural and optical properties of the three compounds. The very basic theoretical knowledge has been described in the beginning that is required for the understanding of the structural and optical properties. The reason for the distortion and anomalous behavior of this class of compounds has been well dealt in the theoretical part. Then the step by step procedure of the preparation of the compounds by solid synthesis route has been explained along with a flow chart for a better understanding. The compounds have been prepared by solid state reaction procedure. All the samples have crystallized in Pnma space group. With the help of XRD pattern analysis Miller indices, particle size, strain and lattice parameters have been found out. SEM images have been used to explain the morphology and the grain size. Further FTIR and RAMAN spectroscopy has been used to study the optical properties, modes of vibrations and the MnO6 octahedral structure.
