Abstract:

In this study, the effect of Sm3+ ions doped in glasses of the composition (40-x)B2O3:40Bi2O3:20BaO:xSm2O3 in mol% (where x = 0, 0.50, 1.00, 1.50, 2.00 and 2.50).The BiBaBO glasses have been prepared by melt-quench technique. The results show the densities and molar volume of glasses are between 4.80-4.91 g/cm3 and 50.19-51.58 cm3/mol, respectively. The absorption spectra consists of ten absorption peaks that are located at 374, 388, 402, 942,1079, 1226, 1405, 1471, 1523 and 1585 nm, and are assigned to 6P7/2, 4G11/2, 6P3/2, 6F11/2, 6F9/2, 6F7/2, 6F5/2, 6F3/2, 6H15/2 and 6F1/2 transitions, respectively. The luminescence spectra exhibited four emission peaks corresponding to the 4G7/2 → 6H5/2 (564 nm yellow, weak), 4G7/2 → 6H7/2 (600 nm orange, strong), 4G7/2 → 6H9/2 (645 nm red, strong) and 4G7/2 → 6H11/2 (709 nm red, weak) transitions.
