A Study of the Optical Properties in ZnWO 4 Nanorods Synthesized by Hydrothermal Method

Abstract

We investigate the effect of synthesized time on the structure, as well as optical properties in ZnWO4 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 ZnWO4 nano-rod can be controlled by adjusting the reaction time. The resultant sample is a pure phase of ZnWO4 without any impurities. The results showed that the optical property of ZnWO4 nanoparticles obviously relied on their rod sizes.
