Sm^(3+)掺杂碱锌硼硅酸盐玻璃的稳定性

Stability study of Sm^(3+)doped alkali zinc borosilicate glass

为了实现纳米半导体微晶在稀土Sm3+掺杂碱锌硼硅酸盐基础玻璃中的受控成核、生长,系统研究了基础玻璃的SiO2与B2O3摩尔比以及BaO、ZnO、La2O3、Y2O3、Nb2O5等不同的网络中间体对玻璃稳定性的影响。研究表明:控制SiO2与B2O3摩尔比以及BaO、La2O3、Y2O3、Nb2O5在玻璃中的掺入量均能提高玻璃的形成能力,增加玻璃的稳定性;不同的组分对于玻璃稳定性的改善也具有不同的机制,但是并不影响玻璃的析晶产物。

For the purpose of nano semi-conducting crystals' controlling generation in the basic borosilicate glass which doped with Sm^(3+), the relations between SiO_2/B_2O_3ratio 、 BaO、 ZnO、 La_2O_3、 Y_2O_3、 Nb_2O_5 and glass stability were systematically studied. The results showed that the appropriate SiO_2/B_2O_3ratio and BaO、 ZnO、 Y_2O_3、 Nb_2O_5 contents can improve the glass stability, and the crystal materials in this glass system are H type and T type SmBO_3.
