In such glass, the content of ionic lead and bismuth, which participate in the glass structure as network formers,is orer 50%.
重金属氧化物玻璃是以PbO、Bi_2O_3为基础的新型玻璃,其中Pb~(2+)、Bi~(3-)离子含量大于50％,并作为网络形成体离子而参与玻璃构成。
The mixed former effect was mentioned firstly and its effects on spectroscopic properties of Er3+ ion were investigated.
提出并研究了Er~(3+)离子光谱性质的混合形成体效应,结果表明Er~(3+)离子在铋酸盐玻璃中通过混合形成体效应可以获得较大的有效线宽(△λ_(eff)=62～80nm)、较高的受激发射截面(σ_e=0。
