制备了30BaO-30Ga2O3-40GeO2-xEr2O3系统玻璃,测量了Er3+在钡镓锗玻璃中的吸收光谱.分别采用488 nm,800 nm和980 nm激发不同浓度Er3+掺杂的玻璃样品,测量了Er3+的4S3/2→4I15/2荧光光谱;并利用488 nm脉冲氙灯激发,测量了Er3+的4S3/2→4I15/2荧光衰减,讨论了Er3+掺杂浓度对4S3/2能级发光强度和荧光寿命的影响.结果表明:随着Er3+浓度的增加,4S3/2→4I15/2荧光强度先增大后减小,在Er3+浓度为1%时出现峰值;而4S3/2能级的荧光寿命呈递减趋势,荧光衰减曲线的非指数成分增加.能量分析表明:Er3+的4S3/2能级和4I15/2能级之间交叉驰豫过程是上转换荧光淬灭的主要通道,而交叉驰豫过程主要源于Er3+电偶极-电偶极间的相互作用.
