Abstract

Optical absorption spectra of triply-ionized praseodymium, neodymium, erbium and thulium ions in different phosphate and sulphate glasses have been studied in the visible and near infrared regions. From the observed positions, Racah ( E1 ,E and E3 ), spin-orbit (ξ4t) and the configuration interaction (α, β) parameters are evaluated. The Judd-ofelt intensity parameters (Ω2Ω4 & Ω6) are determined from the observed intensities of the absorption bands. From the intensity parameters it is found that in Potassium Phosphate-Sodium Phosphate (PPSP) glasses, the environment sensitive parameter Ω2 increases and the vibration dependent parameter Ω6 decreases in the four rare earth ions in the same sequence.
