| 英文摘要 | utilizing mn2+ and tb3+ ions as energy-transfer acceptors, we report a series of emission color-tunable ca2gdzr2(alo4)(3):ce3+, mn2+, tb3+ aluminate garnets. incorporating mn2+ and tb3+ into ca2gdzr2(alo4)(3):ce3+ phosphor generates an orange emission band peaking at 572 nm and a green line peaking at 550 nm. the energy transfers from ce3+ to mn2+ and ce3+ to tb3+ ions are deduced from the spectral overlap between the ce3+ emission and mn2+/tb3+ excitation spectra. fluorescence decay patterns are studied as a function of mn2+ and tb3+ concentration. the calculated values based on the luminescence dynamical process indicate that the intensity ratios of the orange to green bands as a function of mn2+ concentration are in good agreement with those obtained directly from the emission spectra. we have demonstrated that the color emission as well as the luminescence external quantum yield (20.4-48.9%) can be tuned by precisely controlling the content of ce3+, mn2+, and tb3+. the energy transfer significantly enables the achievement of a broad emission spectrum covering an orange spectral region. it is suitable for near-uv light-emitting diode (led) excitation. |
