✦ Synopsis

Dy-doped lead borate glasses were studied. The luminescence spectra showed two characteristic bands at 480 and 573 nm due to 4 F 9/2 -6 H 15/2 (blue) and 4 F 9/2 -6 H 13/2 (yellow) transitions of Dy 3+ . The yellow/blue luminescence of trivalent dysprosium was analyzed as a function of the B 2 O 3 /PbO ratios, the activator (Dy 3+ ) and the PbX 2 (X = F, Cl, Br) content.

Dysprosium-doped heavy metal glasses and transparent glass-ceramics have been investigated using optical spectroscopy. Visible luminescence due to 4 F 9/2 -6 H J/2 (J = 11, 13, 15) transitions of Dy 3+ was registered. Based on excitation and emission spectra as well as luminescence decay analysis, s
