Coupling agent coating method was used to optimize the performance of long-afterglow phosphor materials,and the preliminary reasons were analyzed.Four kinds of coupling agents,KH550,KH560,A151,and A171 were selected to modify the surface of self-prepared strontium aluminate long-afterglow phosphors.It was found that the ratios of coupling agents had a great influence on the luminescence performance of the powder,and the effects of different coupling agents were different.When the dosage of coupling agent was more than 5%,the luminescence performance of the powder was enhanced obviously,and the peak value appeared in 15%～25% ratio.Comparatively,A171 demonstrated the most noticeable optimization effect on luminescent performance overall.
