Density-functional calculations of the electronic structure and atomic positions are reported for Li{sub 2}WO{sub 4}. This compound is found to be very different from the tungstate scintillators such as PbWO{sub 4} in that both the valence and conduction bands are much less dispersive. This leads to a substantially larger band gap. The difference is understood in terms of the crystal structure, in particular, the longer O-O distances connecting the WO{sub 4} tetrahedra.
