【摘要】以Yb3 + Er3 + 共掺的P2 O5 B2 O3 R2 O MO Al2 O3 (R =Li,Na ,K ;M =Zn ,Ca ,Sr,Ba)系统玻璃为研究对象,分别分析了改变B2 O3 的含量,以及加入不同种类的碱金属和碱土金属氧化物对玻璃的物理化学性质的影响。研究结果表明,当B2 O3 的含量增加,玻璃的Tg,Tf 上升,热膨胀系数下降;随着修饰体阳离子半径减小,玻璃的溶解速率下降,化学稳定性变好。更多还原

【Abstract】 The effect of B 2O 3 content and different modifiers on physical and chemical properties of Yb 3+ -Er 3+ co-doped borophosphate glasses system had been discussed in this paper.The result showed that with the increasing of B 2O 3 content,the glass transition temperature(T g) and soft temperatur e(T f) both increased.However,the thermal expansion coefficient decreased.T he density and refractive index were at the minimum value when B 2O 3 and BaO equal to 15.The dissolution rate decreased and chemical durability was better th an before when the radii of modifier ions reduced.更多还原
