Abstract:

Phenomenological even-fold crystal field parameters, Bkm for D2d site symmetry are determined that yield a least-rms deviation of 6.7 cm between calculated and measured energy levels for Er3 in YAsO4. Crystal field components, Akm, are determined by a sum over the YAsO4 lattice, and Bkm are then calculated for the lanthanides in this material. These parameters are used to calculate Stark split energy levels and squared-matrix elements of the electric dipole operator between the energy states for the triply ionized lanthanides in YAsO4.
