Abstract

The visible luminescence of silicate glass (SiO₂ (> 70%)-R₂O₃[B₂O₃, Al₂O₃]-RO[ZnO, MgO, CaO, BaO]-R₂O[Na₂O, K₂O]) doped with various concentrations of dysprosium was investigated. The emission, excitation and absorption spectra, as well as kinetic parameters, were measured over a temperature range from 20 to 300 K. The Judd-Ofelt analysis was applied to the data, in order to calculate transition rates and branching ratios for all observed emission bands. Concentration quenching was experimentally observed at a Dy ion concentration higher than 8 × 10¹⁹ cm^-3 and explained by an analytical model based on the Inokuti-Hirayama theory. The quantum efficiency of visible luminescence and the stimulated emission cross-section at 570 nm were (85 ± 50% and (3.4 ± 0.4) × 10^-21 cm², respectively.
