| 英文摘要 | By introducing the y3+ into sr2p2o7:eu2+, we successfully prepared a kind of new phosphor with blue long-lasting phosphorescence by the high-temperature solid-state reaction method. in this paper, the properties of sr2p2o7:eu2+, y3+ were investigated utilizing xrd, photoluminescence, luminescence decay, long-lasting phosphorescence and thermoluminescence (tl) spectra. the phosphor emitted blue light that was related to the 4f(6)5d(1)-s-8(7/2) transition of eu2+. the bright blue phosphorescence could be observed by naked eyes even 8 h after the excitation source was removed. two tl peaks at 317 and 378 k related to two types of defects appeared in the tl spectrum. by analyzing the tl curve the depths of traps were calculated to be 0.61 and 0.66 ev. also, the mechanism of llp was discussed in this report.
