研究了掺杂 Dy 和 Ce 离子的新型硼酸锂玻璃 (B 2 O 3)-(MO)-(Li 2 O)–(Bi 2 O 3) (其中 M 代表 Ca、Mg 或 Sr) 的光吸收和光致发光性能。这些材料的基本光学吸收边在 315-390 nm 范围内观察到,并且取决于用作网络改性剂的碱土金属的性质。 Dy掺杂玻璃的光致发光光谱揭示了可见光范围内的两个强发射带,对应于Dy 3+ 离子的4 F 9/2→ 6 H 15/2 (486 nm)和4 F 9/2→ 6 H 13/2 (580 nm)跃迁。 Ce掺杂玻璃在可见光范围内显示出一个宽带,对应于Ce 3+ 离子的2 D→ 2 F 5/2 (340 nm)跃迁。对于 Dy 掺杂玻璃,在光谱的近红外区域观察到归因于 Dy 3+ 离子电子跃迁的 3 条光致发光线(980 nm、1010 nm 和 1150 nm),而对于 Dy/Ce 共掺杂玻璃,仅在 1150 nm 处观察到一条光致发光线。讨论了稀土激活剂离子之间激发能量转移的特性。这些玻璃被证明是一种有前途的稀土掺杂基质。
Optical absorption and photoluminescence properties of novel lithium borate glasses,(B 2 O 3)-(MO)-(Li 2 O)–(Bi 2 O 3) where M stands for Ca, Mg or Sr, doped with Dy and Ce ions have been investigated. The fundamental optical absorption edge of these materials is observed in the region of 315–390 nm, and depends on the nature of alkaline-earth metals used as network modifiers. The photoluminescence spectra of Dy-doped glasses reveal two intensive emission bands in the visible range, which correspond to 4 F 9/2→ 6 H 15/2 (486 nm) and 4 F 9/2→ 6 H 13/2 (580 nm) transitions of Dy 3+ ions. Ce-doped glasses show one broad band in the visible range, which corresponds to the 2 D→ 2 F 5/2 (340 nm) transition of Ce 3+ ions. Three photoluminescence lines (980 nm, 1010 nm and 1150 nm) attributed to the Dy 3+ ions electronic transitions are observed in the near-IR region of the spectrum for Dy-doped glasses, while only one at 1150 nm is observed for the Dy/Ce co-doped glasses. Peculiarities of excitation energy transfer between rare-earth activator ions are discussed. These glasses are shown to be a promising host matrix for rare-earth doping.
