Using a mixture of ZnO and Te powders as the source material,ZnO nanoleaves with high yield and uniform morphology are fabricated by thermal evaporation.Each nanoleaf is constructed with a nanowire and a nanodisc on one side of the nanowire near the top.The polygonal nanodisc is in symmetric distribution in relation to the nanowires and has polar planes ±(0001)as surfaces.A local homoepitaxial growth mechanism of ZnO polar nanodiscs induced by Te is proposed.With thin nanodiscs,the ZnO nanoleaves could be used in nanolasers,sensors,and photoelectronic nanodevices.Room-temperature photoluminescence result implies good crystalline quality of the ZnO nanoleaves.
