| 中文摘要 | a series of color-tunable blue-green emitting na2ca4(po4)(3)f:eu2+,tb3+ phosphors were prepared by a high temperature solid-state reaction. their luminescence properties reveal that there is an efficient energy transfer from eu2+ to tb3+ ions via a dipole-quadrupole mechanism where eu2+ ions exhibit a strong excitation band in near ultraviolet (uv) region, matching well with the dominant emission band of near uv (350-420 nm) led chips, and eu2+ and tb3+ ions can give characteristic blue and green emission light. the varied color of the phosphors from blue to green can be achieved by properly tuning the relative ratio of eu2+ to tb3+ dopant through the energy transfer from eu2+ to tb3+ ions. thermal quenching luminescence results reveal that na2ca4(po4)(3)f:eu2+,tb3+ exhibits good thermal stability. these results demonstrate that tb3+ ion with low 4f-4f absorption efficiency in near uv region can play the role of an activator in narrow green-emitting phosphor through efficient energy feeding by allowing 4f-5d absorption of eu2+ with high oscillator strength. the present eu2+-tb3+ codoped na2ca4(po4)(3)f phosphor will have potential application for the near uv white leds.
