  • Abstract

    Sodium-lead-barium-aluminium phosphate (SLBAP) glass doped with tripositive erbium ions have been prepared by melt-quenching technique. The absorption spectral studies of doped SLBAP glass have been performed to compute the phenomenological Judd-Ofelt parameters (Ωλ) and various spectroscopic parameters like Slater-Condon parameter (Fk) k=2,4,6, Lande? parameter (ζ4f) , Racah parameter (Ek) k=1,2,3, nephelauxetic ratio (β?) and bonding parameters (b1/2) to study the local structure of the ligands around the rare earth ion.
