  • Abstract

    The structure and morphology of ZnO nanorods synthesized by hydrothermal method were studied by TEM, XRD and Raman spectroscopy. The Raman scattering spectra at room temperature were excited by He-Ne laser with wavelength 633 nm. The perfect wurtzite structure of ZnO nanorods were verified by the intense E2 (high) mode. The strong red shifts of phonon frequencies, broadening of the FWHM of the Raman peaks and asymmetry of line shapes were attributed to phonon confinement effect. The raman spectrum of ZnO nanorods doped with Mn ions were also studied
