为了研究铁系磷酸盐玻璃的辐射稳定性，我们用稀土元素Ce替代了几种主要的氡系元素。合成了掺Ce的磷铁玻璃。为了模拟反冲原子级联引起的弹道损伤，对纯和掺Ce的铁磷酸盐玻璃进行了重金离子辐照。用能量为750keV、注量为2 × 1015ion/cm~2的金离子辐照纯玻璃和掺Ce玻璃。本文讨论了离子辐照对玻璃网络修饰和网络形成物形态变化的影响。观察到玻璃网络结构和网络形成物的形态发生了显著变化。
To study radiation stability of iron phosphate glasses, cerium is used as surrogate of actinides. Cerium doped iron phosphate glasses have been synthesised. Heavy gold ion irradiations have been performed on pure and cerium doped iron phosphate glasses to mimic ballistic damage due to cascade of recoil atoms. Pure and cerium doped glasses are irradiated with gold ions of energy 750 keV at fluence of 2 × 1015ions/cm2. In this paper, ion irradiation effects on glass network modification and change in speciation of network former have been discussed. Significant changes in glass network structure and speciation of network former is observed.
