Abstract

The spectral kinetic characteristics of the luminescence excited in previously irradiated (≤106 Gy) LiF-O and LiF(U)-O crystals have been investigated in the spectral range 4-1.8 eV by pulsed spectrometry with nanosecond time resolution. The luminescence of the crystals was excited by nanosecond nitrogen-laser or electron-beam pulses at 300 K. The inertial character of uranium luminescence enhancement and the dependence of the number of enhancement stages on the excitation technique are revealed. A difference in the character of the dependences of the intensities of the pulse photo-and cathodoluminescence of uranium on the irradiation dose is found.
