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 (Ω_λ) of the measured absorption spectrum, the radiative transition probability factors (A) and stimulated emission cross-section (σ^E_P) of the observed fluorescent levels have been analyzed. Both emission intensity and measured lifetimes of the prominent luminescent transition (⁴G_5/2 → ⁶H_7/2) concerning Sm³⁺-glass are showing a descending trend with a rise in temperature having a N₂-laser (337.1 nm)as the excitation source.
