A low temperature (600 degrees C) liquid solid reaction method was proposed for the synthesis of SrTiO3 submicron-sized particles from submicron-sized TiO2 powder and different amounts of excess Sr(NO3)(2) (which has a melting point of about 570 degrees C)). The characterization results from X-ray diffraction and field emission scanning electron microscopy revealed that the resultant products were phase-pure perovskite structure SrTiO3 submicron-sized particles with diameters of about 30-108 nm. X-ray photoelectron spectroscopy analysis disclosed that the resultant products had surface compositions slightly deviated from the stoichiometry of SrTiO3. UV-vis absorption spectra of the as-synthesized SrTiO3 submicron-sized particles showed a wide absorption peak centered at around 3.5 or 3.4 eV. (C) 2011 Elsevier B.V. All rights reserved.
