Abstract: ZnO nano/microstructures of different morphologies have been synthesized by using Zn(OH)42- and different ionic liquids with the aid of microwave irradiation. The as-prepared samples are characterized by X-ray diffraction (XRD), scanning electron microcopy (SEM), transmission electron microscopy (TEM), and photoluminescence(PL). The XRD pattern shows that the asprepared samples have hexagonal structures, SEM and TEM images demonstrate that sheet and rod aggregates of ZnO are formed. SAED(selected area electron diffraction) images of rods indicate the single crystal nature, and the PL spectrum of ZnO nanosheet aggregates exhibits a weak ultraviolet emission and a strong green emission at room temperature.

Key words: Ionic liquids, ZnO, Nanomaterials, Microwave heating
