随着 还原性铝粉掺入量 的增加，Eu3+离子 的R值 同样是 在减小，这说明 Eu3+离子 所处 玻璃中 局域环境 对称性提高，因为 玻璃的骨架 是由 SiO4和AlO4四面体 所构成，掺入的 铝粉大部分 被氧化 也成为了 玻璃形成体，使得 玻璃内部结构 更加紧密，所以 R值 会有所降低。
With the increase of reducing aluminum powder dosage, the R value of Eu3+ also decreased, which indicate the local environment of glass where Eu3+ existed enjoyed an increased symmetry. Since the glass skeleton consisted of SiO4 and AlO4 tetrahedrons, most of incorporated aluminum powder were oxidized into glass forming body, which contribute to a more compact glass inner structure, and thus the R value was decreased. |
