【摘要】 采用熔融淬火方法合成了Er³⁺掺杂的组分为xNaPO₃-（80-x）TeO₂-10ZnO-10Na₂O（x=0,10,20,30,40.50,60,70,80）的系列玻璃材料,Er³⁺的摩尔浓度均为1%。测量了玻璃的密度、折射率和吸收光谱。利用标准的Judd-ofelt理论对Er³⁺在该体系玻璃中光学跃迁性质进行了计算,得到了光学跃迁强度参数Ω₂、Ω₄和Ω₆对玻璃组分的依赖关系。计算结果表明:随着玻璃组分的改变Ω₂的变化较大,而Ω₄和Ω₆的变化较小。更多还原

【Abstract】 Er³⁺-doped several glasses with various composition xNaPO₃-（80-x）TeO₂-10ZnO-10Na₂O （where x =0,10,20,30,40,50,60,70,80） were prepared by a melt-quenching technique.The doping concentration of Er³⁺ for all the samples is the same as 1 mol %.The densities,refractive indexes for all the samples were ob- tained.The absorption spectra were measured.Based on the Judd-ofelt theory,the optical transition intensity parameters were calculated.It was found thatΩ₂ changes greatly with the content of sodium metaphosphate, the other parametersΩ₄ andΩ₆ are not sensitive to the host composition variation.更多还原
