Rare Earth Ion-Host Lattice Interactions 14. Lanthanide Pentaphosphates

Abstract

Previously reported spectra of the pentaphosphates of Nd(3+) and Eu(3+) are analyzed by diagonalizing a parametrized C sub S (C sub 1h) Hamiltonian in free-ion bases involving the five and seven lowest J-multiplets, respectively, of each ion. By reassigning symmetries to the reported Eu levels according to predictions from scaled crystal field parameters, B sub km, that fit 28 Nd(3+) levels to 7.61 /cm, a fit of 10.43 /cm to 46 Eu(3+) levels is obtained. Predicted B sub km and energy levels for all the lanthanide pentaphosphates are then obtained.
