Long afterglow yellow luminescence from Pr3+doped SrSc2O4
文献摘要：
A yellow emitting long afterglow luminescence material SrSc2O4∶Pr3+was successfully prepared by solid state reaction method.SrSc2O4∶Pr3+phosphor shows a long afterglow luminescence peak at about 495,545,621,630 and 657 nm,respectively,corresponding to the f-f transitions of Pr3+.The afterglow chromaticity coordinates of SrSc2O4∶1 at％Pr3+were calculated to be(0.35,0.41),indicating that the afterglow emission is close to the light of yellow region.And,the afterglow luminescence of the optimal sample doped by 1 at％Pr3+can persist for over 3 h.The thermoluminescence results suggest that there are three types of traps with depth of 0.61,0.69 and 0.78 eV exiting for all the samples,which are produced by the addition of Pr3+ions.The trap density of SrSc2O4∶1 at％Pr3+is the maximum when the incorporation of Pr3+ions reaches 1 at％,which thus results in the longest afterglow luminescence.All the results indicate that SrSc2O4∶Pr3+can be a potential candidate of novel long afterglow phosphors.
