| 英文摘要 | a series of novel blue long-lasting phosphorescence phosphors sr6al18si2o37:eu2+,re3+ (re3+= ho3+, gd3+, dy3+ and pr3+) were prepared by the conventional high-temperature solid-state reaction in a reductive atmosphere. their properties were systematically investigated utilizing x-ray diffraction (xrd), photoluminescence, phosphorescence and thermoluminescence (tl) spectra. the phosphors emitted blue light that was related to the emission of eu2+ due to 5d-4f transition. bright blue long-lasting phosphorescence (llp) could be observed after the excitation source was switched off. for the optimized sample, the blue long-lasting phosphorescence could last for nearly 4 h in the light perception of the dark-adapted human eye (0.32 mcd/m(2)). the effects of re3+ ions on phosphorescence properties of the phosphors were studied, and the results showed that the co-doping of re3+ ions greatly enhanced the intensity of the peak around 315 k which was related to the long lasting phosphorescence of the phosphors at room temperature and consequently improved the performance of the blue phosphorescence such as intensity and persistent time. |
