EFFECT OF ANNEALING TEMPERATURE ON THE PROPERTIES OF LANTHANUM OXIDE (LA2O3) NANOPLATES BY REFLUX ROUTES

Two-dimensional (2D) crystals, possessing a nano scale dimension have been considered as important new materialsdue to their unique properties and potential applications in electronic and catalysis areas.In this work lanthanum oxide (La2O3) nanoplates were synthesized by a simple reflux method.The approximate band gap of the as-prepared and calcinated samples as calculated from the absorption spectrum are 5.7 and 5.8 nm respectively.Lanthanum oxide (La2O3) nanoparticles were obtained from as-preparedand calcinations of the La2O3 nanoparticles. The as-preparedand calcinations products were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), Band gap was calculated by UVvisible spectroscopy.
