稀土离子掺杂的氧氟玻璃是一种新型上转换发光材料。制备了Tm3+/Yb3+单掺、共掺的摩尔分数为n(SiO2)=0.30,n(PbF2)=0.50,n=(Al2O3)=0.15,n(AlF3)=(0.049-x),n(TmF3)=y,n(YbF3)=x(x=0,0.001,0.010,0.015,0.020,y=0,0.001)系统氧氟玻璃,研究了其上转换发光特性、分析了其上转换发光机理。研究发现,在970 nm抽运光源激发下,Tm3+单掺时没有可见光上转换发射;而加入Yb3+后产生了强的蓝光(452 nm,476 nm)、红光(647 nm)及近红外光(791 nm)发射,分别对应如下辐射跃迁
