【摘要】 研究了掺铒(80-x)P2O5xSiO25Al2O315Na2O(0≤x≤30)玻璃的光谱性能,结果表明SiO2不能明显提高磷酸盐玻璃的光谱性能;选择75P2O55SiO25Al2O315Na2O玻璃组分,研究不同Er3+摩尔分数(0.5%～3%)和不同通气除水时间对光谱性质的影响。实验发现Er3+含量存在最佳值使玻璃的光谱性能最好,通气除水时间增长能明显的提高玻璃的荧光寿命。更多还原

【Abstract】 The influence of SiO₂ content on the spectroscopic property of Er³+ -doped （80-x）P₂O₅-xSiO₂-15Na₂O-5Al₂O₃（x=0,5,10,15,20,25,30） glasses were investigated, the spectroscopic property of 75P₂O₅-5SiO₂-5Al₂O₃-15Na₂O glasses with different Er³+ content（0.5%～3%） and different elimination of OH-time were also discussed. It is found that SiO₂ cannot notably promote the spectroscopic property of phosphate glass. There is an appropriate content of Er³+ in 75P₂O₅-5SiO₂-5Al₂O₃-15Na₂O glasses to get the beat result. 75P₂O₅-5SiO₂-5Al₂O₃-15Na₂O glasses with longer time of elimination of OH-can dramatically promote the radiation lifetime τ_<sup>rad 。更多还原
