Well-defined ZnO and Sm -doped nanorods have been successfully fabricated by a low temperature hyderthermal process. The XRD patterns of both compositions with 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 the reduction of growth rate by the doping of Sm . Ferromagnetism is observed from the results of magnetization measurement. The increase of the saturation magnetization and decrease of coercivity reveal an association with the increase of oxygen vacancies induced by the doping of the Sm in the nanorods.

Mn-doped ZnO (Zn0.97Mn0.03O) nanorods were synthesized by sol-gel method combined with subsequent heat treatment. The structure and optical property of Mn-doped ZnO nanorods were studied by x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscopy (TEM), and fluorescence. The results of electron microscopes illuminate that the Zn0.97Mn0.03O nanorods are prepared at calcinations of 450 under the protection of nitrogen. The Zn0.97Mn0.03O nanorods are composed of small particles of size 20–30 nm. Fluorescence spectra of Zn0.97Mn0.03O nanorods exhibit that there are two very strong blue emission peaks at 451 nm and 461nm except a strong UV emission at 396 nm.

Pure and Fe -doped ZnO nanorod bundles were synthesized in aqueous solution at low temperature, in which inexpensive reagents such as Zn ( NO 3)2, NaOH and Fe ( NO 3)3 were used as precursors. The composition of the final product can be roughly tuned by the precursor ratio used. Energy dispersive X-ray spectroscopy confirms the successful incorporation of Fe element into ZnO nanorods, and X-ray diffraction reveals that ZnO nanorod bundles have a pure hexagonal wurtzite-phase structure. UV–vis spectroscopy show that the spectrum shifts to longer wavelength with increasing iron doping.
