Glasses with chemical composition of (in mol.%): 26 RF-20 PbO-10 TeO 2 –43 H 3 BO 3 –1 EuO 3 (RLTB) were prepared by conventional melt quenching method. The Judd-Ofelt intensity parameters Ω 2 and Ω 6 were obtained from the absorption intensities of 7 F 0 → 5 D 2 and 7 F 0 → 5 L 6 transitions,...
Room temperature visible and near infrared optical absorption and emission spectra of Sm 3+ -doped lead borate titanate aluminum fluoride (LBTAF) glasses with molar composition (50−x) PbO−30H 3 BO 3 −10TiO 2 −10AlF 3 −xSm 2 O 3 (x=0.1, 0.5, 1.0 and 2.0) have been analyzed. Energy parameters for the 4f 5 electronic configuration of Sm...
