Effect of Temperature on the Properties of La2O3 Nanostructures

Abstract In recent years, the synthesis of Lanthanum oxide (La 2 O 3 ) nanoparticles by using simple reflux method using Lanthanum nitrate (LaN 3 O 9 .6H 2 O), urea (NH 2 CONH 2 ) and double distilled water as starting and strong materials. The solution obtained was transferred to a round bottom flask which was maintained at a constant reaction temperature and time. The effect of calcinations temperature on the properties of Lanthanum oxide (La 2 O 3 ) nanoparticles have been explored and reported. The phase and structure of the lanthanum oxide has been identified using X-ray powder diffraction(XRD). The surface properties and morphology has been investigated using a scanning electron microscopy (SEM) technique. The properties of the synthesized nanostructures have been investigated and reported. Fourier transform infrared spectroscopy (FTIR) analysis confirms the present of functional group. The vibrational behaviours of the bonds are further analyzed using FTIR. Thermal stability of the samples have been investigated using TG/DTA analysis and the UV-Vis spectroscopy technique has been exploited to study about the optical absorption of the samples.
