Zn3V2O8 phosphors were synthesized by heat treatment of precursor powders obtained by evaporation of aqueous solutions of peroxo-isopolyvanadic acid and zinc acetate. A precursor solution with a Zn/V molar ratio of 3:1 and a heat-treatment temperature of 600°C gave a powder containing a mixture of Zn3V2O8 and ZnO. The ZnO was removed by treatment with HCl, resulting in a single-phase Zn3V2O8 powder; it showed yellow phosphorescence with a peak at 560 nm at an excitation wavelength of 350 nm.
