Abstract:

We report experimental study of luminescent properties of modern scintillation material SrI2:Eu2+ carried out over the temperature range from 9 to 450 K by the means of the ultraviolet and vacuum ultraviolet spectroscopy with a time resolution. Photoluminescence of the Eu2+ ions at 2.85 eV was studied under both the intracenter and interband excitations, including an X-ray excitation. The bandgap of the SrI2 crystal has been estimated on the basis of the obtained results. In the temperature range below 100 K the intrinsic luminescence at 3.4 eV was revealed and this emission band was assigned by its properties to the luminescence of self-trapped anionic excitons in SrI2. The pronounced manifestation of the effect of multiplication of electronic excitations was revealed in the energy range above 2E(g). (c) 2011 Elsevier B.V. All rights reserved.
