Previous successful analyses of the observed crystal-field structure in Tm3+:LaF3 and Ho3+:LaF3 in an approximate C2v site symmetry have depended on a crystal-field model derived in an analysis of the spectrum of Er3+:LaF3. In the present investigation the predictions of this same model are compared with the observed crystal-field structure in Dy3+:LaF3. The energy parameters resulting from a least-squares fit of the corresponding spectral assignments are reported. To help clarify the physical situation, some comparisons are offered between C2v and D3h crystal-field models for these Ln3+: LaF3 systems.
