Abstract

The morphology controlled the synthesis of La₂O₃ is important for their application in the fields of semiconductors. In this work nanostructured La₂O₃ has been synthesized by reflux method using lanthanum nitrate, urea and double distilled water as starting materials. The approximate band gap of the as-prepared and calcined samples was calculated from the absorption spectrum are 5.8 and 5.9 eV respectively. The as-prepared and calcined products were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR), Bandgap was calculated by UV-visible spectroscopy.
