Persistent luminescence(PersL)materials,as environmentally friendly and energy-saving materials,have broad application prospects in many fields such as lighting,chemistry and even biomedicine.However,studies on the types,performances and mechanism of PersL materials are still insufficient,which signif-icantly restricts their development and application.Under this consideration,we successfully synthesized a yellow PersL material CaSrGa4O8(CSG).The crystal structure was studied in detail through Rotation Electron Diffraction(RED)and Powder X-ray Diffraction(PXRD).What's more,by co-doping Mn2+and Yb3+,the afterglow brightness of CSG could be increased by nearly 20 times,and the afterglow duration could reach more than 6 h.It is worth mentioning that the samples also have excellent performances in mechanical luminescence(ML),photostimulated luminescence(PSL)and cathodoluminescence(CL),which was also investigated systematically.Finally,an anti-counterfeiting label was designed by the samples to reveal the potential of their application in anti-counterfeiting.The results showed that our research not only provided a new candidate PersL material for multifunctional applications,but also gave good help for studying the physical and chemical properties of CSG.
