Structural and optical properties of SrTiO3 nano material obtained by sol-gel method

Abstract

SrTiO 3 (STO) nano particles were prepared by sol-gel process in order to optimize the temperature condition suited for obtaining good quality materials for different applications. The thermal treating condition was selected out through XRD, FTIR and Raman analyses of the synthesized powder. The structural and optical properties of the powder were studied carefully with XRD, SEM, FTIR, Raman and UV-Vis measurements. At optimized annealing temperature (from 900 o C to 1000 o C), the synthesized STO nano particles have a good structure. The shape, size and optical band gap of the obtained material are suitable for further applications.
