Abstract

Novel multicomponent oxybromoborate glasses singly doped with Nd 3+ and Dy3+ ions in the B 2O 3-PbBr 2-PbO-Al 2O 3-WO 3 system have been studied using luminescence spectroscopy. The near-infrared luminescence bands at 901, 1061 and 1335 nm correspond to transitions originating from the 4 F3/2 state to the 4 IJ/2 (J = 9, 11, 13) states of Nd3+ , whereas the visible luminescence bands at 480, 573 and 662 nm are related to the 4 F9/2 - 6 HJ/2 (J = 11, 13, 15) transitions of Dy3+ . Decay curves for 4 F3/2 state of Nd 3+ and 4 F9/2 state of Dy 3+ are nearly single exponential and luminescence lifetimes are close to 86 μs and 400 μs, respectively..
