摘      要：Different morphologies of undoped and transition metals （Mn, Co and Ni） doped one-dimensional （ID） 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.
