| 英文摘要 | Two-photon absorption (TPA) line strengths for transitions within the 4 configuration of Gd3+ have been successfully calculated with several different time-independent perturbation methods. However, attempts to use similar methods to predict TPA line strengths for transitions within the 4f(7) configuration of Eu2+ have been much less successful, due to the fact that the low-lying 4f(6)5d excited states make straight-forward application of perturbation theory unreliable. In this work we carry out a direct calculation of TPA line strengths that take into account the major interactions for 4f(7) and 4f(6)5d configurations nonpertubatively. We also calculate the linewidths of TPA peaks due to nonradiative relaxation to 4f(6)5d energy levels by considering the odd parity vibrations responsible for nonradiative relaxation. Comparisons of calculated TPA line strengths and linewidths with experimental spectra allow improved energy-level assignments. The calculated TPA spectra give a good reproduction of the experimental line strengths, polarization dependences, and linewidths. (c) 2005 Elsevier B.V. All rights reserved. |
