In recent years, there is a constant quest for newer materials with improved properties for technological developments to meet the new demands of tomorrow's society. The basic understanding about the operating/manufacturing process and functional/cost requirements of materials is essentially required to develop and to enhance the properties of the existing materials composition for newer applications. Therefore, an absolute characterization of the newer materials is required before, during and after the fabrication. In the present work nano perovskites are prepared by using SOLID STATE (SS) and SONOCHEMICAL (SC) reaction methods. The complete characterization of prepared perovskite samples is done by the studies such as density, XRD, FTIR, SEM and TEM. Magnetic studies of the prepared samples were carried out with the help of VSM. Photoluminescence properties of the prepared samples were analysed by using Photoluminescence (PL) spectrometer. Efforts are also made to emphasize the structural behaviour of nano perovskites.
