Abstract

Single crystals of Yb2+-doped LiCaAlF6 were gown by the Czochralski technique under CF4 atmosphere. Photoluminescence, thermally stimulated luminescence and decay kinetics of Yb2+ centre in the LiCaAlF6 host were measured in the 4-300 K temperature interval. Phenomenological two excited-state-level model is introduced to obtain quantitative characteristics of the excited state dynamics of Yb2+. The role of Yb2+ centre in trapping processes is discussed. Moreover, defect centres related to LiCaAlF6 host were found. (C) 2003 Elsevier Ltd. All rights reserved.
