Crystal and surface structures of Y2O3 nanoparticles at room temperature

In this work, the crystal and surface structures of Y 2 O 3 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 Y 2 O 3 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 Y 2 O 3 compound being in the range 20–40 nm are of [Formula: see text] nm size.
