Strontium titanate(SrTiO3)was successfully coated on the surface of barium titanate nanoparticles(BaTiO3 NPs)via a sol-gel approach.Microstructure and elemental analysis of the as-prepared material were characterized by X-ray Diffractometry(XRD),Scanning Microscopy(SEM),Transmission Microscopy(TEM),and Energy Dispersive Spectroscopy(EDS).
