Research on the Relationship between Electronic Polarizability and Optical Basicity of Binary Glasses

采用熔融冷却法制备Bi2O3-B2O3二元系统玻璃.基于Lorentz-Lorenz方程计算Bi2O3-B2O3玻璃氧离子电极化率.利用所计算的氧离子电极化率计算Bi2O3-B2O3玻璃的光学碱度,并且讨论Bi2O3-B2O3玻璃氧离子电极化率、光学碱度和折射率之间的关系.

The ternary system of Bi2O3-B2O3 glasses are prepared by melt-quenching method. For binary Bi2O3-B2O3 glasses, the average electronic polarizability of the oxide ion has been calculated on the basis of Lorentz-Lorenz equation. The optical basicity A of the Bi2O3-B2O3 glasses has been estimated on the basis of average electronic oxide polarizability. Furthermore,close correlations are also studied among A α,and n.
