英文摘要 | a novel silicate long-lasting phosphorescence phosphor ca14mg2(sio4)(8):eu2+, dy3+ was prepared by high-temperature solid state reaction. its properties were investigated systematically by powder x-ray diffraction patterns, rietveld refinements, photoluminescence spectra, long-lasting phosphorescence spectra, phosphorescence decay curves, and thermoluminescence spectra. under the excitation of 400 nm, ca14mg2(sio4)(8):eu2+, dy3+ phosphor exhibits green light with the peak at 505 nm, which is attributed to the 4f(6)5d(1)-4f(7) electronic transition of eu2+ ions. it is also found that ca14mg2(sio4)(8):eu2+, dy3+ phosphor can emit green persistent phosphorescence after the irradiation of ultraviolet or visible light is stopped. and for the optimal sample, the green persistent luminescence can last for about half an hour. the co-doping of dy3+ ions greatly enhances the intensity and duration of the persistent luminescence in ca14mg2(sio4)(8):eu2+, dy3+ phosphor. however, the peak position of the long-lasting phosphorescence spectrum is red shift compared to that of the photoluminescence spectrum, and the possible reason was analyzed. meanwhile, the long-lasting phosphorescence mechanism of this phosphor was also discussed.
