Notes:
The Judd–Ofelt analysis has been applied to the sigma-polarized absorption spectrum of Nd3+:NaB‘alumina to determine the modified Judd–Ofelt parameters Ωσ,2, Ωσ,4, and Ωσ,6. A model for the near-neighbor environment of Nd3+ has been proposed and tested using a simplified point charge model for the crystal field. The model indicates that the observed spectrum may be explained by a large linear field term in the crystal field induced by the shift in position of conduction plane oxygen and neodymium ions away from sites of inversion symmetry.
