Abstract
Soda-lime-silicate glasses with the compositions of (65-x)SiO 2-25Na2O-10CaO-xDy2O3 (where x = 0.0, 0.10, 0.30, 0.50 and 1.00 mol % ) were prepared by melt-quenching technique and characterized. The density (ρ) and molar volume (VM) obtained were found to increase with increasing Dy2O3 content. Such behaviour was accounted for by the differences between atomic weight and the atomic radii of the Si and Dy ions. The rare-earth ion concentration (N) and ionic radius (rp) were calculated. The absorption spectra of Dy3+ doped soda-lime-silicate glass correspond with several bands, which are assigned from the ground state, 6H 15/2 to 4I13/2, 4F7/2(389 nm), 4I15/2 (453 nm), 6F3/2 (744 nm), 6F5/2 (797 nm), 6F7/2(892 nm), (6H7/2, 6F9/2)(1082 nm), ( 6F11/2, 6H9/2)(1266 nm), and 6H11/2 (1649 nm). The refractive index of glasses was increased with the increasing of Dy2O3 concentration. © 2010 Published by Elsevier Ltd.
