摘要：
Fe-substituted ZnWO4 as a possible optical material has some interesting properties. We report a comparison of luminescence properties of pure ZnWO4 and Zn0.99Fe0.01WO4 powders synthesized with aqueous salt metathesis reaction in this work. The experimental results indicated that the Fe-substitution results in decreases in the crystallinity and grain size. In comparison with the pure ZnWO4, the Zn0.99Fe0.01WO4 powder shows a small intensity of blue-green emission band, significantly smaller intensity of emission peaks at longer wavelength, large half-widths of the emission bands, and a red emission band at a range of 590-680 nm. The results clearly indicate that the red emission band is related to the Fe3+ cation.
