Description

Zinc oxide (ZnO) nanorods and nanosheets were grown via hydrothermal process on ZnO seed layers synthesized by spin-coating technique on silicon and glass substrates with different precursor concentrations of zinc acetate dihydrate. The concentrations of zinc acetate dihydrate in solution were varied from 6 mM to 500 mM. The ZnO seed layers, ZnO nanorods, and ZnO nanosheets were characterized by field-emission scanning electron microscope (FESEM) and X-rays diffractometer (XRD) to study morphology and crystallographic structure, respectively. The results showed that particle size and diffraction pattern of ZnO seed layers changed with various precursor concentration. Moreover, different precursor concentration affected the change of ZnO morphology from nanorods to nanosheets.
