Rare Earth Ion-Host Lattice Interactions. 8. Lanthanides in YPO4.
Abstract
Even-fold crystal-field parameters (even-k B sub km) were found that gave least rms deviations of less than 10/cm between calculated and measured energy levels for Nd(3+) and Ho(3+) in YPO4. Linear interpolation and extrapolation yielded even-k B sub km for the triply ionized lanthanides Pr through Tm in YPO4. Energy levels predicted with these B sub km for Er, Tm, and Eu were in close agreement with measured energy levels for these ions. Crystal-field components (A sub km) were determined by a sum over the YPO4 lattice. These A sub km were used with appropriate B sub km, radial integrals, and energy positions of the higher electronic configurations to calculate squared matrix elements of the electric dipole operator between the Stark split energy states of the ground configuration for the triply ionized lanthanides in YPO4.
