Abstract

We report the optical characterization of Sm3+: SiO2+Al2O3+Li2O+Na2O+MgO glass from the measurements of optical absorption spectra (at 300 K), total luminescence spectra (10 K - 300 K) and fluorescence lifetimes (10 K - 300 K) 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 (Omega(lambda)) of the measured absorption spectrum, the radiative transition probability factors (A) and stimulated emission cross-section (sigma(P)(E)) of the observed fluorescent levels have been analyzed. Both emission intensity and measured lifetimes of the prominent luminescent transition ((4)G(5/2) —> H-6(7/2)) concerning Sm3+ - glass are showing a descending trend with a rise in temperature having a N-2-laser (337.1 nm) as the excitation source.
