Sulfate replacement of potassium dihydrogen phosphate (KDP) was studied by the first-principles simulation method and the density of of its states was calculated. We found that sulfate can reduce the band gap of KDP crystal to 3.90eV (318nm), which is consistent with the experimental work of others and indicates that sulfate may be a source of the low damage threshold.
