Περίληψη:	Dysprosium-doped borophosphate glasses, containing the divalent cations Mg2+, Ca2+, Sr2+, Ba2+, and Zn2+, are prepared by the melt-quenching technique. The structure of the glasses is investigated by Raman, infrared, and nuclear magnetic resonance (NMR) spectroscopies and the fluorescence properties are determined. The Dy3+ emission lifetime increases with an increasing ionic field strength and its maximum is observed in the Mg2+ and Zn2+ containing glasses. This result can be explained by the stronger M-O bonding which causes a rearrangement of the borophosphate network and creates a local Dy3+ environment of comparably low symmetry. This is in agreement with the Raman spectra and the evolution of the molar volume. The effect of the B/P variation on the emission properties of Dy3+ is investigated in a second series of glasses where the emission lifetime is found to be maximum at 10 mol% B2O3.
