ZnWO 4 nanocrystals have been prepared via a hydrothermal route, and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy. The size and morphology of ZnWO 4 nanocrystals were found to depend on the reaction temperature and pH. The length of ZnWO 4 nanorod increased with the increase in pH of the hydrothermal solution. An unusual nanoparticle-to-nanorod transformation was observed during the formation of ZnWO 4 nanoparticles at pH 11.0 and 180 °C. Luminescent properties of ZnWO 4 nanocrystals were investigated by photoluminescence (PL) spectroscopy.
