最后,作者对比了不同还原性铝粉掺入时,当掺入量在3mol%以下时,大部分Al粉氧化成为AlO4四面体进入玻璃结构中充当玻璃形成体;而当Al粉掺入量高于3mol%时,可能一部分Al进入到玻璃结构中形成AlO6六面体充当玻璃形成体,使得玻璃内部结构有序性降低,同时也使得Eu离子所处环境对称性变差,Eu3+离子的R值反而升高。
Finally, the authors compared the different amounts of incorporated reducing aluminium powder to the glass. When the incorporated amount was less than 3 mol%, a majority of the aluminium was oxidized into AlO4 tetrahedron and entered into glass structure and functioned as structural elements of the glass. On the other hand, when exceeded 3 mol%, a portion of the aluminium could enter the glass as AlO6 hexahedron structural elements, which reduced the order of internal structure of the glass, at the same time, reduced the environmental symmetry for Eu ions, hence, increased the R value for Eu3+ ions. |
