Preparation and characterization of perovskite LaAlO3 nanocrystals

The aim of said study was to obtain nanostructured LaAlO3 through self combustion synthesis using lanthanum nitrate, aluminium nitrate as precursors and glycine as a fuel, without the subsequent heat treatments after synthesis. The temperature variation with respect to a sample with constant molar ratio was investigated. The crystallinity ( phases present and crystallite size: estimated by single-line method ) of the product obtained was determined by X-ray diffraction (XRD) measurement, thermogravimetric analysis(TG-DTA),scanning electron microscope(SEM),and transmission electron microscopy (TEM). The synthesis method facilitated the production of Perovskite LaAlO3 with crystallite size between 40-70 nm.
