摘要
分别掺有磷和硼的二氧化硅经γ辐照后产生多种顺磁性中心,ESR研究指出氧空穴O^-主要稳定在杂质离子附近.O_2^-自由基稳定在Si离子上.F心的研究认为氧缺位俘获电子存在一个动态平衡过程.
ESR method was used to study the properties of paramagnetic centers generated by y- irradiating silica gel containing respectively phosphorus and boron as impurity ions. Oxygen holes O- were found to be stablized close to impurity ions. In addition, O2- radical and F colour center signals were observed and investigated. A dynamic equilibrium process would exist during F centers formation.
