Résumé

Er3+doped sodium lead antimonite glass have been prepared and analyzed by (UV-Vis-NIR) absorption, near infrared luminescence and fluorescence decays. The optical band gap and refractive index were calculated from the (UV-Vis-NIR) absorption. The Judd-Ofelt theory has been applied to compute the J–O intensity parameters Ωt (t= 2, 4, 6) from absorption spectrum and determine the spectroscopic parameters such as the radiative transition probability (Arad), radiation lifetime (τ) and branching ratio (β) of Er3+ transition. Experimental lifetime of the glass for the transition between 4I13/2 and 4I15/2   level was calculated from the photoluminescence decay curves and estimated the quantum efficiency. Absorption, emission and gain cross-section, effective band width (Δλeff) and gain band width of the 4I13/2 ®4I15/2   transition of Er3+ in glass are recorded and calculated. The obtained results confirm the potential of this glass in signal amplification and laser application.
