Thermal, structural and optical properties of Dy 3+ -doped alkali fluoroborate glasses with composition (in mol%), 49B 2 O 3 +25XO+25NaF+1Dy 2 O 3 (where X=Li 2 , Na 2 , K 2 , Mg and Ca), have been investigated. Thermal analysis revealed the homogeneous formation of the glasses. The FTIR spectra reveal that the glasses contain BO ...
Borate glasses doped with trivalent europium were prepared by the conventional melt quenching technique, in the chemical composition of (49.99-x)B 2 O 3 +25Li 2 O+25LiF+xEu 2 O 3 by varying the concentration of the rare earth ion in the order 0.01, 0.1, 1, 2 and 3wt% and their structural, luminescence and thermal behavior have been reported. The XRD and FTIR...
