SPECTROSCOPIC PROPERTIES OF SM3+ DOPED IN YTTERBIUM LEAD LITHIUM BISMUTH SILICATE GLASSES

Abstract

Glass sample of Ytterbium Lead Lithium Bismuth Silicate (50-x) Bi2O3:10PbO:10Li2O: 10Yb2O3: 20SiO2: x Sm2O3. (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 Sm3+ doped Ytterbium lead lithium bismuth silicate glasses have been recorded at room temperature. The various interaction parameters like Slater-Condon parameters Fk (k=2,4,6), Lande parameters (ξ4f), nephelauexetic ratio (β'),bonding parameters (b 1/2)and Racah parameters E k (k=1,2 3) have been computed. Judd-Ofelt intensity parameters and laser parameters have also been calculated.
