Al3+ (2−8 mol%) sensitized ZnWO4:Eu3+(4 mol%) red emitting phosphors were synthesized by the hydrothermal method. The samples were well crystallized in the pure monoclinic wolframite structure with P2/c space group. The nanoparticals were characterized by X-ray diffraction (XRD), scanningelectron microscope (SEM), UV-Visible spectroscopy (UV-Vis) and photoluminescence (PL) properties.The red emission of Eu3+ and Al3+ co-doped ZnWO4 under the excitation at 393 nm can be promissing candidate for red phosphor materials for white LED (Light Emitting Diode). Moreover, the photocatalyric activity of the samples were estimated against methylene blue (MB - cationic) dyepollutant under ultra-violet (UV) lamp irradiation at room temperature. The dye remove efficiency of approximately 98% offers an effective approach to remove organic contaminants in industrial wastewater.
