| 中文摘要 | sr3mgsi2o8:ce3+, dy3+ phosphors were prepared by a solid-state reaction technique and the photoluminescence properties were investigated. the emission spectra show not only a band due to ce3+ ions (403nm) but also as a band due to dy3+ ions (480, 575nm) (uv light excitation). the photoluminescence properties reveal that effective energy transfer occurs in ce3+/dy3+ co-doped sr3mgsi2o8 phosphors, and the co-doping of ce3+ could enhance the emission intensity of dy3+ to a certain extent by transferring its energy to dy3+. the ce3+/dy3+ energy transfer was investigated by emission/excitation spectra, and photoluminescence decay behaviors. in sr2.94mgsi2o8:0.01ce(3+), 0.05dy(3+) phosphors, the fluorescence lifetime of dy3+ (from 3.35 to 27.59ns) is increased whereas that of ce3+ is greatly decreased (from 43.59 to 13.55ns), and this provides indirect evidence of the ce3+ to dy3+ energy transfer. the varied emitted color of sr3mgsi2o8:ce3+, dy3+ phosphors from blue to white were achieved by altering the concentration ratio of ce3+ and dy3+. these results indicate sr3mgsi2o8:ce3+, dy3+ may be as a candidate phosphor for white light-emitting diodes. copyright (c) 2012 john wiley & sons, ltd. |
