%X Single crystalline Fe-doped ZnO nanocantilever arrays have been synthesized by thermal evaporating amorphous Zn-Fe-C-O composite powder. The characterizations of composition, structure and phonon spectrum properties of the nanocantilevers have been performed. Arrays of uniform, perfectly aligned and single-crystal nanowires have been observed by electron microscopy. The results of the X-ray photo-electric spectra and the Raman spectrum provide the evidence that Fe is incorporated into the ZnO lattice at Zn site. Abnormally, the room temperature UV emission band of Fe-doped ZnO nanocantilevers disappears and the green one has a large red-shift, and the intensity of the green emission is strongly quenched because the Fe3+ enters the ZnO crystal lattice.
