A new luminous materialSrAl2O4:Eu2+,Dy3+/light conversion agent that can emit red light in the darkness after being ex-cited was fabricated by combining light conversion agent on to SrAl2O4:Eu2+,Dy3+particles through YsiX3. The morphology of the luminous materials was analyzed by scan electron microscopy (SEM). The emission behavior was evaluated by fluorescence spec-trophotometric analysis and the results demonstrated that the emission spectra of samples had a redshift compared to SrAl2O4:Eu2+, Dy3+ and the emission intensity rose dramatically atfirst and then decreased when the ratio of light conversion agentdoping was over 1.4 wt.%. And the emission color of SrAl2O4:Eu2+,Dy3+/light conversion agent was tuned from green (SrAl2O4:Eu2+,Dy3+) to or-ange-red. Furthermore, the afterglow property was also investigated, and the results indicated that the afterglow brightness reached 6.5 cd/m2, and as the light conversion agent concentration increased the brightness intensity decreased.
