Excitation and luminescence of Dy^3＋ ions in PbO-P2O5-Ga2O3 glass system

Lead phosphate glasses singly doped with Dy^3＋ ions were studied. The samples were prepared in a glove box in order to eliminate hydroxyl groups. Local structures were examined using FT-IR. Excitation and luminescence spectra for Dy^3＋ ions in inves- tigated lead phosphate glasses were registered. Luminescence intensity ratio Y/B related to 4F9/2→^6HJ/2 （where J=15, 13） transitions was determined and luminescence lifetime （ζm） for the 4F9/2 state of Dy^3＋ions were also measured.
