[The time-delay fluorescence phenomenon of SrFCl0.5Br0.5:Sm2+].
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.
