| 摘 要： | 低温77K下,在三种玻璃中都观察到了Co2+的ESR信号,认为Co2+是处干四面体格位,从实验所得的有效g值,判别出中心离子与配位体间化学键的性质变化,本文还研究了氟磷酸盐玻璃中Ni2+ESR,辨认了Ni2+的谱线,用自旋哈密顿作了比较详细的分析计算,并解释了一般氧化物玻璃中很难观察到Ni2+的ESR的原因。

| Abstract: | The BSE of Co2+ in the three kinds of glass has been observed at 77 K, it is shown that the Co2+ ions are mostly situated on tetrahedral sites. We conclude the order of the effective g value obtained from the experiments is related to a slight change of the chemical bonding nature between the central ions and the ligands. In addition, the ESR of Ni2+ in fluorophosphate glass has been observed and its spectrum is identified. A detailed calculation with the spin-Hamiltonian is carried out, and it explains why the ESR signal of Ni2+ in most oxide glasses can hardly be observed. |
