In the present work, zinc tungstate (ZnWO 4 ) nanoparticles were synthesized by a simple co-precipitation technique without the addition of any templates and complexing agent. The X-ray diffraction study confirmed the formation of monoclinic structure ZnWO 4 . The annealing temperatures play a signi...
