Controlled growth of ZnO nanomaterials via doping Sb

ZnO nanomaterials with wurtzite structure were synthesized by simple thermal evaporation method from pure Zn or Zn–Sb alloys with three Sb/Zn mole ratios (1:50, 1:15, 1:6) at the same eperimental conditions. XRD patterns, Raman spectra and XPS analysis clearly indicate that Sb element has been doped...

Description
Summary:ZnO nanomaterials with wurtzite structure were synthesized by simple thermal evaporation method from pure Zn or Zn–Sb alloys with three Sb/Zn mole ratios (1:50, 1:15, 1:6) at the same eperimental conditions. XRD patterns, Raman spectra and XPS analysis clearly indicate that Sb element has been doped into the ZnO lattice. As the Sb/Zn mole ratio of the evaporated materials increases, the Sb content doped into the ZnO lattice increases, and the shape of ZnO nanomaterials varies from tetrapod-shaped whisker, nanorod (aspect ratio 5:1 or 2:1) to hexagon nanoplate, which implies that the shape of the ZnO nanomaterials could be controlled via doping Sb. Finally, the controlled growth mechanism of ZnO nanomaterials was discussed in detail.
