摘要：

La2O3-Fe2O3 composite nano-pseudo-spheres with a core-shell structure were prepared by the hydrothermal process in the presence of cetyltrimethyl-ammonium bromide. X-ray diffraction (XRD), transmission electron microscope (TEM), selected area electron diffraction (SAED), magnetic properties measurement system and UV-vis spectrum were employed to characterize the morphology, structure, magnetic properties and performance of optical absorption of the nano-pseudo-spheres materials. Moreover, a rational mechanism is proposed and the influence factors for the morphology control of La2O3-Fe2O3 composite nano-pseudo-spheres are also preliminarily presented.
