In this work, we report on the simple synthesis of Terbium doped zinc tungstate (Tb:ZnWO۴) nanocrystals for optical application. The structure, and optical properties of the synthesized nanopowders(NPs) were investigated. The prepared Tb:ZnWO۴ NPs were in a pure monoclinic crystalline phase with crystallite size of ۷۳ nm. The FESEM image indicated the presence of spherical/cubic nanoparticles with an average particle size of ۹۵-۱۱۰ nm. Under UV irradiation, a considerable luminescence emission was observed in the blue/green spectral regions. The facile synthesized luminescent nanoowders provides promising applications in future optical sensors.
