摘要：

The experimental Stark energy levels for the Nd3+ and Er3+ in LiRP4O12 crystals were presented in our previous paper [13]. A crystal field analysis of these data is based on a Hamiltonian of C2 point group symmetry, including J-mixing effects. We find that the twinned C2/C (C2) structure is consistent with all available experimental results. A Hamiltonian parametrized in monoclinic symmetry was used to describe the observed crystal-field splittings of Nd3+ and Er3+ in LiRP4O12. Resulting RMS deviations between calculated and experimental levels range from 6.8 to 7.4 cm-1.
