Zinc tungstate (ZnWO4) single crystals have an intrinsic luminescence at 480 um which is utilized in their application in scintillator devices. A broad component of luminescence which peaks at about 635 nm at 77 K is shown to result from molybdenum impurity ions. The molybdenum luminescence can be excited in the transparent optical range of ZnWO4 close to its absorption edge. The molybdenum emission has a resolvable doublet structure and a decay time of 145 μs at 300 K and 800 μs at 77 K, which is long compared with the intrinsic luminescence decay.
