Crystal and surface structures of Y2O3 nanoparticles at room temperature

Abstract

In this work, the crystal and surface structures of Y2O3 nanoparticles were explored. The exploration of crystal structure was carried out by X-ray diffraction method at room temperature and under normal conditions. It was found that the crystal structure of the Y2O3 compound has a cubic symmetry with an Ia-3 space group. The lattice parameters have the values: [Formula: see text] Å. The surface structure was studied at room temperature and under normal conditions on Scanning Electron Microscope (SEM) microscope. It was found that the nanoparticles of the Y2O3 compound being in the range 20–40 nm are of [Formula: see text] nm size.
