考虑到基于折射率的氧化物离子极化率α O-2-(n(0)) 获得的值，提出了二元氧化物玻璃的分类。光学碱度Lambda(n(0))、金属化标准M(n(0))、相互作用参数A(n(0))、离子的有效电荷以及通过XPS测定的Ols和金属结合能。已经建立了四组氧化物玻璃：由两种形成玻璃的酸性氧化物形成的玻璃；由形成玻璃的酸性氧化物和改性剂的碱性氧化物形成的玻璃；由形成玻璃的酸性氧化物和条件形成玻璃的碱性氧化物形成的玻璃；由两种碱性氧化物形成的玻璃。还估计了电子离子极化率在氧化物玻璃化学键合中的作用。与之前有关简单氧化物分类的结果有很好的一致性。所获得的结果可能为基于折射率预测氧化物玻璃中的键合类型以及预测新型非线性光学材料提供良好的基础。 (c) 2005 Elsevier Inc. 保留所有权利。
A classification of binary oxide glasses has been proposed taking into account the values obtained on their refractive index-based oxide ion polarizability alpha O-2-(n(0)). optical basicity Lambda(n(0)), metallization criterion M(n(0)), interaction parameter A(n(0)), and ion's effective charges as well as Ols and metal binding energies determined by XPS. Four groups of oxide glasses have been established: glasses formed by two glass-forming acidic oxides; glasses formed by glass-forming acidic oxide and modifier's basic oxide; glasses formed by glass-forming acidic and conditional glass-forming basic oxide; glasses formed by two basic oxides. The role of electronic ion polarizability in chemical bonding of oxide glasses has been also estimated. Good agreement has been found with the previous results concerning classification of simple oxides. The results obtained probably provide good basis for prediction of type of bonding in oxide glasses on the basis of refractive index as well as for prediction of new nonlinear optical materials.
