Abstract EN
We investigated the influence of the pH value, precursor concentration (C), growth time and temperature on the morphology of zinc oxide (ZnO) nanostructures.
The pH of the starting solution was varied from 1.8 to 12.5.
It was found that the final pH reaches an inherent value of 6.6 independently of the initial pH solution.
Various ZnO structures of nanotetrapod-like, flower-like, and urchin-like morphology were obtained at alkaline pH (8 to 12.5) whereas for pH solution lower than 8 rod-like nanostructures occurred.
Moreover, we observed the erosion of the nanorods for a pH value less than 4.6.
By changing the concentrations the density and size were also varied.
On going from a high (C>400 mM) to lower (C<25 mM) C, the resulted ZnO nanostructures change from a film to nanorods (NRs) and finally nanowires (NWs).
It was also found that the length and diameter of ZnO NRs follow a linear relation with time up to 10 hours, above which no further increase was observed.
Finally the effect of growth temperature was seen as an influence on the aspect ratio.
