3. Results and Discussion
3.1 Morphologies and structure(SEM)
Fig. 1 (a)shows SEM image of as-obtained ZnO nanowires of in the first step ranging from 80 to 400 nm in diameters and about 4 mm in length. Gold particles at the tips of the nanowires can be seen in Fig. 1(a). This indicates that the ZnO nanowire growth was governed by a VLS process. Fig. 1(a) shows ZnO nanowires obtained under th
