Spectral and Up conversion Properties of Eu3+ Doped in Zinc Lithium Potassiumniobate Borosilicate Glasses

Abstract

Abstract: Glass sample of zinc lithium potassiumniobate borosilicate (35-x) SiO2:10ZnO:10Li2O:10K2O:10Nb2O5:25B2O3:xEu2O3. (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 and fluorescence spectra of three Eu3+ doped zinc lithium potessiumniobate glasses have been recorded at room temperature. The various interaction parameters like Slater-Condon parameter F2, Lande parameter (ξ4f), nephelauexetic ratio (β') and bonding parameter (b 1/2) have been computed. Judd-Ofelt intensity parameters and laser parameters have also been calculated.
