title: Optical properties of lead borate glasses containing Dy(3+) ions.
abstract: Optical properties of lead borate glasses containing Dy(3+) ions were examined using absorption and luminescence measurements and theoretical calculations based on the Judd-Ofelt framework and the Inokuti-Hirayama model. The luminescence spectra show two characteristic bands at 480 and 573 nm, which are due to (4)F(9/2)-(6)H(15/2) (blue) and (4)F(9/2)-(6)H(13/2) (yellow) transitions of trivalent Dy(3+) ions. The yellow/blue luminescence and its decay were analyzed as a function of activator concentration.
