摘要

Nd(OH)(3) particles of nanometer size have been prepared by using different methods. The obtained neodymium hydroxide samples have been investigated by using the FT-Raman spectroscopy, X-ray diffraction, transmission electron microscopy as well as field emission electron microscopy. Observable changes in enhanced electronic Raman bands have been found among the FT-Raman spectra of different morphological Nd(OH)(3) particles which formed under different physical-chemical conditions. The result suggests that the change of size and morphology of Nd(OH)(3) particles occur with structural change and subtle variation on the coordination environment around the neodymium ions.
