The optical properties and structural relationships of ternary meta‐ and pyro‐phosphate glasses are found to be correlated with electronic polarizability. In particular, the optical properties of photoelasticity and refractivity have similar tendencies with electronic polarization evolution, which can be estimated from the Lorentz–Lorenz equation and the compositional data of reported electronic polarizability with small corrections with structural viewpoint. Combinations of the oxide constituents of BaO, SnO, and ZnO result in systematic changes of optical properties, which can be attributed to the phosphate‐anion network revealed by ³¹P magic‐angle spinning nuclear magnetic resonance spectroscopy. The small photoelastic constants are obtained with the ubiquitous high polarizable cation of Ba²⁺ and the substitution of Sn²⁺ with Zn²⁺ in the ternary phosphate glasses.

三元磷酸盐玻璃的电子极化率，光弹性和折射率之间的关系

发现三元偏焦玻璃和焦磷酸盐玻璃的光学性质和结构关系与电子极化率相关。尤其是，光弹性和折射率的光学性质与电子极化演化具有相似的趋势，这可以根据洛伦兹-洛伦茨方程和报告的电子极化率的组成数据进行估算，并从结构的角度进行小幅校正。BaO，SnO和ZnO的氧化物成分的组合导致光学性质的系统变化，这可以归因于³¹ P魔角旋转核磁共振波谱揭示的磷酸根阴离子网络。Ba ²⁺随处可见的高极化阳离子可得到较小的光弹性常数在三元磷酸盐玻璃中用Zn ²⁺取代Sn ²⁺。
