  • Abstract

    Tripositive neodymium ion doped sodium-lead-barium-aluminium phosphate (SLBAP) glass has been prepared by melt-quenching technique. The final composition (by weight) was approximately Na(PO3)670%-BaO15%-PbO 10%-Al2O3 5%-R Ln (Where R=0.5% and Ln= Nd+3). The absorption and Fluorescence spectra in the range of 200 to 800 nm at room temperature of doped SLBAP glass have been recorded to compute 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.
