Rapid synthesis of ZnO micro/nanostructures in large scale

X-ray powder diffraction (XRD) patterns and field emission scanning electron microscopy (SEM) investigation reveal that large-scale ZnO micro/nanostructured materials have been successfully synthesized via a microwave method within a few minutes. The morphology is controllable and could be easily manipulated by simply varying the reaction time. And a possible formation process is proposed. The room temperature photoluminescence (PL) spectra have also been examined to explore the optical property. The present synthesis method possesses several advantages, which would be significant to the deeper study and wide application of ZnO in the future. It is also envisioned that this method could provide a facile approach to synthesize other desired materials of controllable morphology in a short time.
