Luminescence behavior of Dy3+ ions in lead borate glasses

Dy-doped lead borate glasses were studied. The luminescence spectra showed two characteristic bands at 480 and 573 nm due to F-4(9/2)-H-6(15/2) (blue) and F-4(9/2)-H-6(13/2) (yellow) transitions of Dy3+. The yellow/blue luminescence of trivalent dysprosium was analyzed as a function of the B2O3/PbO ratios, the activator (Dy3+) and the PbX2 (X = F, Cl, Br) content. (C) 2009 Elsevier B.V.
