本文用顺磁共振方法研究了含碱金属和碱土金属的二元、三元磷酸盐玻璃以及多元氟磷玻璃在γ辐照下产生的顺磁色心性质.实验表明,两种玻璃在γ辐照后都存在两种不同类型的色心——电子型色心和空穴型色心.它们的g值为2.004～2.123;观察到色心与磷核P~(31)(I=1/2)的超精细相互作用,分析实验结果认为:磷玻璃中的共价键要比氟磷玻璃强.并根据杂化轨道理论估算了磷玻璃中处于缺陷位置的键角.

In this paper, a study on the properties of colour renter in phosphate glasses and polynary fluorophasphate glasses, which contain alkali and alkaline earth metal elements,using ESR method is presented. The experimental results show that there are two types of colour center in such two kinds of glasses, after irradiation with ?-ray. One is the trapped electron type, other is the hole type. Their g values are from 2.123 to 2.004. Hyperfine interaction of colour centers with phosphate nucleus (P31) has been observed. Analysis shows that the covalent bond in phosphate glasses； is stronger than that in fluorophosphate glasses. According to the orbital hybridization theory, the bond angles at the site of the defect in phosphate glasses are calculated.
