Abstract

Results are presented from analyzing the structural and luminescent properties of Ce, Gd co-doped aluminoborosilicate glasses. It is shown that the intensity of luminescence inherent in oxygen-deficiency centers grows along with simultaneously occurring Ce, Gd ions and a nonlinear change in their concentration. This phenomenon correlates with the nonlinear change in glass polymerization and the number of highly symmetrical positions of Gd³⁺ ions. The co-doping effect can be explained by the coexistence of different structural positions of co-dopant ions in a alumino-borosilicate glass matrix and their interaction with intrinsic defects observed in it.

内在缺陷对含稀土离子硼硅玻璃结构和光学特性的影响

摘要本文介绍了分析掺杂铈、钆的硅酸铝玻璃的结构和发光特性的结果。结果表明，缺氧中心固有的发光强度随着同时出现的 Ce、Gd 离子及其浓度的非线性变化而增长。这一现象与玻璃聚合的非线性变化和 Gd3+ 离子高度对称位置的数量相关。这种共掺杂效应可以用共掺杂离子在铝硼硅酸盐玻璃基体中不同结构位置的共存以及它们与基体中观察到的固有缺陷的相互作用来解释。
