Luminescence Properties of Ga2O3-B2O3-GeO2-SiO2 Glass Doped with Dy3+ and Tb3+

Abstract

采用高温熔融法分别制备了高含量Tb^3+单掺和Dy^3+/Tb^3+共掺的镓硼锗硅酸盐(GBSG)发光玻璃,并分析了其光谱性能。根据Dy^3+和Tb^3+掺杂的镓硼锗硅酸盐(GBSG)玻璃的激发和发射光谱、荧光寿命衰减曲线等特性,探讨了Dy^3+与Tb^3+之间的能量传递关系。结果表明:玻璃的发光强度和荧光寿命随着Tb^3+、Dy^3+含量的增加而减少。与相同摩尔浓度的单掺玻璃相比,共掺玻璃发光强度的衰减速率先减慢而后加快。Tb^3+、Dy^3+离子之间的能量传递方式为无辐射共振能量传递和~4F92)+~7F6→~6H(15/2)+~5D4交叉弛豫效应。
