摘要：

The present study was carried out by means of the low temperature time-resolved luminescence UV-VUV spectroscopy as well as the optical and thermally activation spectroscopy. The Ce3+ centers in regular lattice sites and located in the vicinity of the point defects of crystal structure were observed. Spectral and kinetic characteristics of the luminescence of these centers were defined. A photoluminescence of new point defects of the crystal structure are also manifested. We evaluated the energy of the interband transitions as E-g approximate to 6.2 eV in LaBr3. At the excitation energies E-exc>13 eV ( higher than 2E(g)) the effect of the electronic excitations multiplication was detected.
