摘 要：Different morphologies of undoped and transition metals（Mn,Co and Ni） doped one-dimensional（1D） ZnO nanocrystals were successfully synthesized by chemical method in an air atmosphere using polyvinylpyrrolidone（PVP） as a surfactant.The structure and optical properties were studied by scanning electron microscopy（SEM）,transmission electron microscopy（TEM）,X-ray diffraction（XRD）,thermal gravimetric analysis（TGA）,ultraviolet visible（UV-vis） absorption spectra and photoluminescence（PL） spectra.The doped ZnO nanorods exhibited a blue-shifted band gap and enhanced ultraviolet（UV） emission.In addition defect related emission was observed for the doped ZnO.
