Manganese-doped zinc oxide tetropods were fabricated of pure ZnO,MnO,and graphite power mixtures on a silicon wafer coated with a thin layer of copper as catalyst through vapor-phase transport method.The morphology,structure,and composition of samples were measured and examined by x-ray diffraction pattern,electron diffraction pattern,scanning electron microscopy picture,and high revolution transition electron microscopy images.Compared with un-doped samples fabricated under the same conditions,PL spectrum,and mechanism were analyzed by the combination of Raman scattering spectra and photoluminescent excitation spectra.The results that Mn-doped samples,showing hexagonal hollow shape with multitips at the front and inner,are composed of wurtzite ZnO growing along[0001] direction;both intensity and width of UV band reduced,and a new emission peak at 415 nm emerged,were observed from Mn-doped samples′ PL spectrum.According to analysis based on Raman scattering and photoluminescent excitation spectra measurement,these properties should be attributed to the function as nonradiation recombination centers and d-d transition from excited states to ground state of Mn2+ s,which were placed substitutionally in a cation site of ZnO host lattice.
