Abstract
The synthesis of SrTiO3 nanocubes have been carried out by solvothermal process using cetyl trimethyl ammonium bromide (CTAB) as capping agent to control the particles morphology. The condition of the synthesis was obtained at 160 ºC for 24 hours with molar ratio of SrTiO3 and capping agent was 1 : 1. The X-ray diffraction (XRD) pattern shows that SrTiO3 adopts a perovskite structure with a higher intensity of 110 at 2q:32.33º and the crystallite size calculated from FWHM was found to be 41 nm. Fourier transform infrared (FTIR) spectrum shows a shift in particular absorption band attributed the interaction between SrTiO3 particles surface and the head group of CTAB molecules. Transmission electron microscopy (TEM) image shows the cubic-like particles of SrTiO3, this indicatesthat CTAB successfully functions as capping agent on the synthesis of SrTiO3.

We report on the synthesis of SrTiO3 nanocubes via solvothermal method using cetyltrimethyl ammonium bromide (CTAB) as capping agent
The diffraction peaks are well-defined at 2 : 22.03 (100), 32.33 (110), 39.92 (111), 46.40 (200), and 57.81 (211) that can be indexed as a cubic perovskite SrTiO3.The present of impurity peaks in all samples refer to SrCO3
Summary
The research in nanotechnology describes the creation and exploitation of materials with structural features in between those of atoms and bulk materials and advanced functional application. Great effort has been carried out to synthesizing various inorganic materials with controlled shape and size as well as multivarious structural engineering, which are expected to offer superior properties for various applications
