Abstract A set of Nd3+ doped vanadium arsenate glasses having formula 25%As2O3.70%V2O5. (5-x) %CuO.x%Nd2O3 (where x = 0, 0.5, 1, 1.5, 2 mol%) are manufactured by the ordinary melt quenching technique. These glasses are investigated by several tools. Complete amorphous phase is confirmed for all samples. The calculated optical basicity decreases with the increase of Nd2O3 mole% in the glasses, while the molar refractive index follows an opposite trend. The metallization criterion calculation confirms the insulating nature of the samples, and such nature increases with increasing the Nd2O3 content. Tg, Tc and thermal stability of the glasses are found to increase with increasing the Nd2O3 content in the glasses. Continuous addition of the Nd3+ ions increases the thermal conductivity of the glasses from 0.11 to 0.178 W/m.oC. Emission spectra due to 365 nm excitation light demonstrates emission peaks around 506, 542, 580 and 635 nm from the samples.

Nd3+离子对一些As2O3.V2O5.CuO玻璃结构、物理和发射特性的影响

摘要 一组Nd3+掺杂的砷酸钒玻璃，其分子式为25%As2O3.70%V2O5。(5-x) %CuO.x%Nd2O3（其中 x = 0, 0.5, 1, 1.5, 2 mol%）通过普通熔体淬火技术制造。这些玻璃通过多种工具进行研究。所有样品均确认为完全无定形相。计算出的光学碱度随着玻璃中 Nd2O3 摩尔％的增加而降低，而摩尔折射率则呈相反的趋势。金属化标准计算证实了样品的绝缘性质，这种性质随着 Nd2O3 含量的增加而增加。发现玻璃的 Tg、Tc 和热稳定性随着玻璃中 Nd2O3 含量的增加而增加。Nd3+ 离子的连续添加将玻璃的热导率从 0.11 增加到 0.178 W/m.oC。
