Abstract AITranslate

Sr2MgSi2O7∶Eu2+,Dy3+,Yb3+long afterglow phosphors were prepared via high-temperature solid state reaction.Microstructure and optical properties of Sr2MgSi2O7∶Eu2+,Dy3+,Yb3+long afterglow phosphors were characterized through XRD,SEM,excitation spectrum,emission spectrum and decay curves.The results show that the crystal structure and microstructure of Sr2MgSi2O7∶Eu2+,Dy3+,Yb3+have not changed significantly.The addition of Yb3+ions shows a remarkable change in fluorescent properties and afterglow performance.The introduction of Yb3+makes Sr2MgSi2O7∶Eu2+,Dy3+,Yb3+have better fluorescence performance and afterglow properties.Different Yb3+doping amounts have a significant effect on the trap depth and electron transport rate of the long afterglow phosphors.When the doping amount of Yb3+equals to 0.03,experiments show that the Sr2MgSi2O7∶Eu2+,Dy3+,Yb3+has the strongest fluorescence intensity and the best afterglow attenuation performance.
