摘要
研究了添加ＳｉＯ＿２对ＰｂＯ－Ｂｉ＿２Ｏ＿３－Ｂ＿２Ｏ＿３玻璃结构和荧光性能的影响，发现用ＳｉＯ＿２取代部分Ｂ＿２Ｏ＿３时，［ＳｉＯ＿４］四面体与［ＢＯ＿３］三角形相连接并进入玻璃的结构网络中。随着ＳｉＯ＿２引入量的增加，８＿２Ｏ＿３的减少，玻璃结构更紧凑，密度增加。发射光谱表明，玻璃的最大发射峰位置随ＳｉＯ＿２的引入而向长波方向移动。
The effects of addition of SiO_2 on the structure and luminous property of PbO-Bi_2O_3-B_2O_3 system glasses were studied. It is found that,when part of B_2O_3 is replaced by SiO_2, [SiO_4] connects with [BO_3] and enters the structure network of glass,With the increasing of SiO_2 content, the glass structure becomes more com-pact,resulting in the increasing of density of the glass. The emission spectra show that the maximum emission peak of glass shifts in the direction of longer wavelength with the addition of SiO_2.
