Abstract: 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.

Key words: ZnWO4, Nanorod, Photoluminescence
