Effects of Preparation Conditions on the Morphology and Photoluminescence of ZnWO_4 Nanocrystals

ZnWO4 nanorods were prepared via a hydrothermal route,and characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),and scanning electron microscopy(SEM).The morphology of ZnWO4 nanocrystals were found to depend on the reaction time and pH.Luminescent properties of ZnWO4 nanocrystals were investigated by photoluminescence(PL)spectroscopy.
