Structural and luminescence properties of Nd3+-doped PbO-B2O3-TiO2-AlF3 glass for 1.07 μm laser applications

► The intensity and radiative parameters are obtained applying the Judd-Ofelt theory. ► Effect of Nd3+ concentration on luminescence and decay times has been discussed. ► Major laser transition for Nd3+ ion in LBTAFNd glasses is 4F3/2→4I11/2 (1.07 μm). ► The LBTAFNd05 glass is a suitable candidate for 1.07 μm laser applications.
