Abstract

Glass sample of Zinc Lead Lithium Borotengsten Tellurite (35-x) TeO2: 10ZnO: 10Li2O:10PbO: 15Wo3:20
B2O3: x Tb2O3. (where x=1,1.5,2 mol%) have been prepared by melt-quenching technique. The amorphous
nature of the prepared glass samples was confirmed by X-ray diffraction. The absorption spectra of three Tb3+
doped zinc lead lithium borotengsten tellurite glasses have been recorded at room temperature. The various
interaction parameters like Slater-Condon parameters F2, Lande' parameter (ξ4f), nephelauexetic ratio (β'),
bonding parameter (b1/2) and Racah parameters Ek
(k=1, 2, 3) have been computed. Judd-Ofelt intensity
parameters Ωλ (λ = 2, 4, 6) and laser parameters have also been calculated. The spectroscopic quality factor
related with the rigidity of the glass system is also discussed
