Assignment of 4f -> 5d excitation spectra of Nd3+ in crystals using the simple model

摘要

The measured low-temperature (4f)(3)->(4f)(2)5d excitation spectra of Nd3+ doped in crystals YPO4, CaF4 and LiYF4 [van Pieterson et al, Phys. Rev. B 65 (2002) 045113] are assigned and analyzed using the simple model proposed by Duan et al. [Phys. Rev. B 66 (2002) 155108] and Ning et al. [J. Alloy. Compd. 366 (2004) 34]. The agreement between theoretical and observed energies and intensities are acceptable, and at the same time the spectra are assigned in more detail. (c) 2005 Elsevier Inc. All rights reserved.
