摘　　要：利用传统方法制得了高Sm2O3含量的硼硅酸盐玻璃,讨论了稀土含量以及玻璃组成对稀土玻璃吸收光谱曲线的影响。结果表明:钐硼硅酸盐玻璃的特征吸收峰强度随着Sm2O3含量的增加而增强,同时吸收峰展宽;随着硅硼比的增加,也使得吸收峰的宽化程度增加。为制备对特定波长激光具有高吸收强度的特种光学玻璃提供了依据。The borosilicate glass with high doped Sm_2O_3 was fabricated with traditional method, and the influence of glass components and rare earth content on absorption spectrum was discussed. With the increasing of Sm_2O_3 content, the intensity of characteristic absorption peak is increasing and the absorption peak is broadened. Meantime it was found that improving of SiO_2/B_2O_3 ratio, the broadening degree of absorption peak is increasing. The experimental results provided the methods for making special optical glasses which have the characteristics of high absorption for special wavelength.
