英文摘要	Er3+的4I 13/2能级寿命的长短对评估Er3+掺杂材料在光通讯波段的应用十分重要。基于980nM双脉冲注入式ld激发下的Er3+激发态吸收上转换发光,测量在不同双脉冲时间间隔下的上转换红光发光强度,再根据上转换红光的发光强度随双脉冲时间间隔的变化关系,推导出了Er3+红外4I 13/2能级寿命的拟合公式,实现了红外能级寿命的可见区测量。因此,结合兼具时间间隔可调和同步脉冲取样的双脉冲注入式ld模块和光电倍增管(r2658),就可以实现所有Er3+红外能级寿命的测量,这是一种十分经济的微秒量级荧光寿命测试系统。; The lifetime of Er3+ and 4I13/2 energy level is of very significance for evaluating the application potential of Er3+-doped materials in optical communication.In the present article,based on the Er3+ excited state absorption upconversion(UC) luminescence under 980 nm double-pulse injection LD excitation,the authors detected the red UC luminescence intensity under different time gap between double pulses,then according to the dependence between UC red luminescence intensity and time gap between double pulses,deduced the fitting formula for obtained medial energy level lifetime of Er3+,and actualized the measurement of infrared level lifetime in visible region.So,combining photomultiplier tube(R2658) with double-pulse injection LD module with controllable time gap and synchronous pulse sample,we can obtain all the infrared level lifetime of Er3+,and this is a cost saving lifetime measurement system with μs resolution.; 国家自然科学基金项目(61102030)资助
