摘要

在本文中，我们制备了成分为（75-x）TeO2–5Nb2O5–20ZnO–xNa2O mol%（x=7、10、15和18）的玻璃。研究了法拉第效应，并用拉曼光谱分析了这些玻璃的结构。可以观察到，当Na2O浓度从7mol%增加到18mol%时，Verdet常数的值从0.113min/G.cm降低到0.071min/G.cm。这一结果可以解释为：当向玻璃基质中添加Na2O时，导致非桥接氧（NBO）的存在。717–721 cm−1范围内的峰值（d）与TeO3（tp）相中含有非桥氧的Te-O键和Te=O键的拉伸振动有关。

Magento optical properties and structure of tellurite glasses modified by alkaline ions

In this paper we prepared glasses with composition (75-x)TeO2–5Nb2O5–20ZnO–xNa2O mol%, (x = 7, 10, 15, and 18) were synthesized by using the conventional quench-melting method. The Faraday effect has been investigated as well as the structure of these glasses was analyzed by Raman spectroscopy. It can observe that when the Na2O concentration increased from 7 to 18 mol%, the value of the Verdet constant decreased from 0.113 to 0.071 min/G.cm. This result can be interpreted as the following: when adding Na2O into the glass matrix, leads to the attendance of non-bridging oxygens (NBO). The peak (d) in the range of 717–721 cm−1 is related to the stretching vibrations of Te˗O˗ and Te=O bonds containing nonbridging oxygen in TeO3 (tp) phase.
