Abstract:
The lithium sodium borate glasses doped with Eu3+ ion are prepared using melt quenching technique, their structural and optical properties have been evaluated. The density of prepared glasses exhibits an inverse behavior to the molar volume ranging from 2.26 g/cm3 to 2.43 g/cm3 and 26.95 cm3 /mol to 26.20 cm3 /mol, respectively. The absence of sharp peaks in XRD patterns confirms the amorphous nature of the prepared glasses. The absorption spectra yield four transitions centered at 391 nm (7F05L6), 463 nm (7F05D2), 531 nm (7F05D1), and 582 nm (7F05D0). The most intense red luminescence is observed at 612 nm corresponding to 5D07F2 transition under 390 nm laser excitations.

摘要:
使用熔融淬火工艺制备了掺杂铕离子的硼酸锂钠玻璃, 同时对其结构和光学性能进行了评价。随着Eu3+的掺杂比由0.3mol%增加到1.0mol%, LNB玻璃摩尔体积由26.95 cm3/mol 变成26.20 cm3/mol,密度从2.26 g/cm3变为到2.43 g/cm3.XRD图谱没有出现尖锐的谱峰, 证实了玻璃呈现不定性.吸收光谱出现四个变化峰391 nm (7F05L6),463 nm(7F05D2),531 nm (7F05D1)和582 nm (7F05D0).在390 nm激光激发下612 nm 呈现5D07F2转变.
