Abstract

This paper presents a study on the spectroscopic and radiative properties of Nd 3+ ions in sodium-borate glasses (B 2 O 3 -Na 2 O-PbO-ZnO-Li 2 O). The thermal behaviors of the sample glasses were observed using thermogravimetric analysis (DTA) and a -12% total mass changes was recorded during a thermal treatment from 75°C to 900°C. The Judd-Ofelt parameters (Ω 2,4,6 ) have been computed from the experimental and theoretical oscillator strengths, as well as from the optical absorption spectra. Several important radiative properties such as radiative transition probability (A R ), branching ratio (β R ), emission cross section (σ e ) and fluorescence lifetime (τ) of the 4 F 3/2 → 4 I 11/2 transition have been obtained and compared with other glasses from previous studies. The calculations of emission cross section and quantum efficiency have shown that the 1.0 mol.% Nd 3+ -doped glass makes a good potential laser candidate at the 4 F 3/2 → 4 I 11/2
