掺铝钕高硅氧玻璃的制备及光谱性能研究

Preparation and Spectrum Properties of Nd^(3+)/Al^(3+)-codoped High Silica Glass

采用分相酸溶工艺制备了Na2O-B2O3-SiO2体系纳米多孔玻璃,并以此为基质进行了钕铝掺杂的实验,制备了掺钕铝高硅氧玻璃,光谱分析表明,所制得的玻璃在1064 nm附近有明显的发射峰。研究了掺杂浓度、烧结气氛对玻璃光谱性能的影响,分析了铝离子在共掺杂玻璃中的作用。结果表明在浓度为0.2 mol/L的Nd(NO3)3溶液中制备的掺杂高硅氧玻璃发光强度最强,还原气氛下烧结的掺杂高硅氧玻璃光谱强度高于在空气中烧结得到的高硅氧玻璃,同时在还原条件下铝离子能够明显的提高玻璃的发光强度。

The Na2O-B2O3-SiO2 glass system nano-porous glass was prepared by using Split phase acid dissolving process in this paper and in which as the substrate Nd3 ＋/Al3 ＋-codoped experiment was carried out,preparing the Nd3 ＋/Al3 ＋-codoped high silica glass, spectrum analyses shows the glass had significantly emission peak near 1064 nm. Doping concentration and the influence of sintering atmosphere on the spectral performance of glass were studied,the role of aluminum ions in doped glass was analyzed.Results show that the spectral intensity of high silica glass sintered under the reducing atmosphere is higher than in the air,The best neodymium doped concentration is 0. 2 mol /L,aluminum ions can significantly improve the luminous intensity of the glass under the condition of reduction at the same time.
