| 英文摘要 | in this paper, a novel divalent europium-doped green emitting blue convertible k2ba7si16o40:eu2+ phosphor has been synthesized successfully via high-temperature solid-state reaction. the structure of k2ba7si16o40:eu2+ has been refined on the basis of x-ray powder diffraction by rietveld refinement method, which consists of two infinite dimensional layers of corner-sharing [sio4] tetrahedral parallel to (201) linked together through eight-coordinate k and seven- and nine-coordinate ba atoms. under excitation of blue light, the k2ba7si16o40:eu2+ phosphor emits a strong green emission band peaking at 500 nm. the concentration quenching mechanism of the eu2+ ion was discussed and the critical distance was calculated. furthermore, the phosphor exhibits high quantum efficiency and good thermal stability, indicating that the k2ba7si16o40:eu2+ phosphor can serve as an effective green emitting candidate for blue light down-conversion white light emitting diodes. |
