Abstract:

The chrysanthemum-like ZnO crystal has been grown by dry oxidation process in the sol–gel method. The samples have been characterised using SEM and XRD. The surface morphology of SEM result shows that the structure is like a chrysanthemum flower. The chrysanthemum-like crystal has been synthesised and composed of one-dimensional nanorods which have hexagonal wurtzite structure. It is also shown that the nanorods were preferentially grown along the [001] direction. In this paper, the growth mechanism and synthesis technique of chrysanthemum-like nanostructured ZnO are explained in detail.
