Abstract :

Undoped and chromium (Cr) doped SrTiO3 (STO) nanoparticles were synthesized by coprecipitation method. The cubic structure and perovskite phase were confirmed by X-ray diffraction (XRD). The crystallite size of STO is 45 nm and when Cr ion concentration is increased, the crystallite sizes also increased. The nanoparticles are observed from SEM analysis and the purity of the undoped and doped samples are confirmed by EDS spectrum. The dielectric constants are increased at low frequencies when increase the Cr ions in the STO matrix.
