【摘要】 本文运用Cu²⁺在玻璃中的吸收光谱与顺磁共振谱研究了 Na₂O-B₂O₃-SiO₂ 玻璃的结构与组成的关系。获了得在 B₂O₃含量为 25mol％附近g₁ 因子有一转折,而在A₁ 及光吸收峰的能量的变化曲线上则呈现极小值。此外,当Na₂O 与B₂O₃ 的比例小于0.5时,这些参数的变化比较显著。上述变化是与玻璃结构内不同硼氧和硅氧基团的变化有关。更多还原

【Abstract】 The relationship between the structure and composition of glasses in the systemNa₂O-B₂O₃-SiO₂ has been studied by measuring optical absorption and ESR of Cu²⁺.It isfound that, when B₂O₃ content is about 25 mol%,there is an abrupt change on the g₁ curveand a minimum value appears on the A₁ curve,and so does the peak energy of opticalabsorption.Moreover, these parameters vary markedly when the ratio of sodium oxide toboron oxide is less than 0.5.Such variation is related to the structural changes of borateand silicate groups in the glass.更多还原
