Abstract
A novel and simple approach is reported to fabricate uniform single-crystal ZnO nanorods in ionic liquids. The as-obtained ZnO nanorods have been characterized by XRD, TEM, HRTEM, SAED, XPS, EDXA, PL and UV-vis absorption spectra. The rod diameters of the nanostructures can be controlled by tuning the amount of sodium hydroxide in the synthesis. Photoluminescence results show that the nanostructural ZnO exhibits better optical properties than bulk ZnO does and interestingly, the smaller the rod diameters are, the better optical property 1D nanostructural ZnO exhibits. The possible growth mechanism of ZnO nanorods is also investigated.
