Rare Earth Ion-Host Lattice Interactions 11. Lanthanides in Y3A15O12.

Abstract

Previously reported spectra of triply ionized lanthanides in yttrium aluminum garnet (YAG) are analyzed theoretically by diagonalizing a parametrized D sub 2 Hamiltonian in a free-ion wave-function basis involving the lowest 10, 11, 9, 10, and 10 J-multiplets respectively of Nd, Eu, Tb, Dy, and Er. The best-fit crystal field parameters for all but Dy are then used to obtain a quadratically smoothed set of parameters for all the lanthanides. It was shown that a coordinate system can be chosen in which the crystal field is primarily D sub 2d. By using the D sub 2d approximation, squared-matrix elements of the electric dipole operator between the Stark split energy states are computed for all the lanthanides in YAG. (Author)
