摘要：

Temperature dependent transient curves of excited levels of a model Eu3+ complex have been measured for the first time. A coincidence between the temperature dependent rise time of the D-5(0) emitting level and decay time of the D-5(1) excited level in the [Eu(tta)(3)(H2O)(2)] complex has been found, which unambiguously proves the T-1 -> D-5(1) -> D-5(0) sensitization pathway. A theoretical approach for the temperature dependent energy transfer rates has been successfully applied to the rationalization of the experimental data. (C) 2013 Elsevier B.V. All rights reserved.
