Paper Abstract

We report the optical characterization of Sm3+:SiO2 + Al2O3 + Li2O + Na2O + MgO glass from the measurements of optical absorption spectra, total luminescence spectra and fluorescence lifetimes of the prominent emission transitions of the Sm3+ ions. Besides the analysis of spectral properties, physical and nonlinearity characterizing property parameters have also been computed to understand the optical dispersive power of this glass. By the application of Judd-Ofelt parameters (Ωλ) of the measured absorption spectrum, the radiative transition probability factors (A) and stimulated emission cross-section (σEP) of the observed fluorescent levels have been analyzed. Both emission intensity and measured lifetimes of the prominent luminescent transition (4G5/26H7/2) concerning Sm3+-glass are showing a descending trend with a rise in temperature having a N2-laser (337.1 nm)as the excitation source.
