Lead phosphate glasses singly doped with Dy3+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 Dy3+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 (τm) for the 4F9/2 state of Dy3+ions were also measured.
