Paper Abstract

The luminescence dampness of PbWO4 crystals upon their excitation by H+ ion beam during prolonged time intervals was studied. An exponential law for the luminescence yield reduction at a density of the beam proton irradiation of j approximately equals 6 X 1012 ion/cm2 was registered, with the yield falling to a final value of J(infinity ) approximately equals 1/3 X J0. Similar kind modification of the luminescence yield suggests that some channels of the radiative relaxation process for intermediate excited states in the PbWO4 bandgap could be clocked in part by local high energy excitation produced by energetic protons in the unit cells of lead tungstate.
