英文摘要:
Effects of substitutions of SiO2 for Al2O3 and P2O5 in a single base phosphate glass, Nd3+: P2O5-Al2O3-Li2O-MgO-Sb2O3, on glass structure and properties are investigated. For glasses with Al2O3 replaced by SiO2, coordination number of Al becomes larger, and P=O bond and Si with six oxygens coordinated emerge. For glasses with P2O5 replaced, coordination number of Al becomes smaller, P(Q(2)) changes to P(Q(1)) and all Si units are four coordinated. The reason for coordination number of Al and Si change may come from the variation of terminal oxygen quantity. The relationship between glass structure and physical (rho, T-g, CTE), mechanical (E), and optical properties (n(D), sigma(em), Delta lambda(em)) are builded.
