摘要 | Nanocrystalline Yb2O3 of various particle sizes was prepared using sol-gel method. XRD analysis shows that the prepared nanocrystalline Yb2O3 is cubic in structure with space group Ia3. TEM photographs indicate that Yb2O3 nanoparticles are basically spherical in shape. Calculation of crystallite size indicates that the average crystallite size of Yb2O3 increases with increasing calcination temperature, but the average crystal lattice distortion rate decreases with increasing calcination temperature and crystallite size. This result shows that the smaller the crystallite size, the bigger the crystal lattice distortion, and the worse crystal growth. Solubility test of Yb2O3 in nitric acid shows that the surface activity of Yb2O3 increases with decreasing crystallite size. Fourier Transform Infrared Spectrometer (FTIR) spectra reveal that nanocrystalline Yb2O3 has higher surface activity; than that of ordinary Yb2O3. Absorbance intensity of Yb-O bond of nanocrystalline Yb2O3 is weaker than that of ordinary Yb2O3, and the absorbance of Yb-O bond of nanocrystalline Yb2O3 is small blue-shifted. |
