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 UV-visible spectroscopy.
