| Abstract: | Large-scale flower-shaped Mn doped ZnO nanostructures have been grown on silicon substrates by simple thermal evaporation at atmospheric pressure.The flower-shaped nanostructure makes up of many nanorods,which are rooted in one center.Analysis of X-ray diffraction,high-resolution transmission electron microscopy and Raman spectra results reveal that the products are of single phase with wurtzite structure.Elemental mapping results show that no impurity clusters exist in the doped materials.The photoluminesc... |
