Effect of transition metal ion substitution on structure and optical properties of ZnWo4 material

In this presentation, we investigate the effects of transition metal (Fe, Co, Ni) substitution on structure and optical properties of ZnWO4 nanopowder prepared using the hydrothermal method. The prepared powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman scattering and optical absorption spectra.
