英文摘要	a new long-lasting phosphorescence phosphor ca9bi(po4)(7):eu2+,dy3+ was synthesized by solid state reaction and its long-lasting phosphorescence properties were investigated for the first time. the x-ray powder diffraction, photoluminescence, long-lasting phosphorescence spectra, decay curves and thermoluminescence curves were measured. the ca9bi(po4)(7):eu2+,dy3+ phosphor exhibits an asymmetric emission centered at 475 nm, which can be ascribed to the 4f(6)5d(1)-4f(7) electronic transition of eu2+. for the optimized sample, the bright bluish green long-lasting phosphorescence could be observed for 5 h by naked eyes after the excitation source was removed. the long-lasting phosphorescence spectra show that the co-doping of dy3+ ions greatly enhance the intensity of the long-lasting phosphorescence. meanwhile, the long-lasting phosphorescence mechanism of this phosphor was discussed. based on our study, dy3+ ions are suggested to increase the density of electron or hole traps so as to improve the performance of the bluish green phosphorescence of eu2+, including the intensity and persistent time.
