Abstract Although the sensitivization mechanism of the excitation of manganese in calcium sulfate phosphors is considered to be the most probable [1] it has not been sufficiently confirmed by direct luminescence measurements, and in certain cases, the results of these measurements contradict each other. In [4] the sensitivizing action of the WO 4 −2 group on the luminescence of the Mn2+ ion was established for mixed phosphors based on calcium sulfate and tungstenate, but this effect was not studied in detail. Previously, we observed lattice-defect sensitivization of the radioluminescence of Mn2+ in radioactive CaSO4·Mn phosphors [5]. On the other hand, the work of Rudolph and Ruffer [2] on the cerium sensitivization of Mn2+ luminescence is not confirmed by other researchers [3]. In the same work it was shown that Pb, Sn, and Bi also sensitivize Mn2+ luminescence in CaSO4.
