Abstract
We investigate the effect of synthesized time on the structure, as well as optical properties in ZnWO<sub>4</sub> nano rod prepared by hydrothermal method. The prepared rods were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman scattering, absorption and photoluminescent (PL) spectra techniques. The size and morphology of ZnWO<sub>4</sub> nano-rod can be controlled by adjusting the reaction time. The resultant sample is a pure phase of ZnWO<sub>4</sub> without any impurities. The results showed that the optical property of ZnWO<sub>4</sub> nanoparticles obviously relied on their rod sizes.
