Antimony and vanadium are observed to reduce the colour of ZnWO4 single crystals. It is suggested that charge compensation for these dopants may occur via the substitution of OH- ions for O2-. The structure and the angular dependence of the IR absorption bands, as well as OH-OD exchange experiments, are in accordance with this charge-compensation mechanism.
