| 摘 要： | 本文报道了ＳｒＦＣｌ０．５Ｂｒ０．５：Ｓｍ＾２＋材料中Ｓｍ＾２＋的荧光光谱，并由光谱中几个较强的荧光峰的时间分辨光谱得到荧光的寿命。通过对连续光激发的荧光谱与脉冲光激发的荧光谱的比较发现了延迟光现象。并对不同延时时间的光谱作了比较，并进一步分析了延迟荧光产生的原因是来源于各辐射荧光的上能级粒子数布局方式的不同造成的。

| Abstract: | In this paper the Sm2+ fluorescence spectra SrFCl0.5Br0.5:Sm2+ is reported. Based on some stronger fluorescence peaks of time-distinguished spectra, the life of the fluorescence is achieved. Compared the fluorescence spectra stimulated by the continuous light with the fluorescence spectra stimulated by pulse, the phenomenon of delay fluorescence is discovered and it's reason comes from particle distribution of different energy levels. |
