摘要：
Well-defined ZnO and Sm-doped nanorods have been successfully fabricated by a low temperature hydrothermal process. The XRD patterns of both compositions with a single diffraction peak (002) show the same wurtzite hexagonal structure. The radius of Sm-ZnO nanorods observed by FE-SEM is smaller than that of pure ZnO, indicating a reduction of the growth rate by the doping of Sm. Ferromagnetism is observed from the results of the magnetization measurements. The increase of the saturation magnetization and decrease of coercivity reveal an association with the increase of oxygen vacancies induced by the doping of Sm in the nanorods.
