采用固相反应法成功合成了具有高效白光光致发光性能的新型单相荧光粉Ca 2NaMg 2-V3 O 12:xSm 3+。通过X射线粉末衍射(XRD)证实了单一Ca 2NaMg 2 V3 O 12相的形成。波长可调谐的白色光是通过耦合500 nm处的宽发射带和564、616、650和708 nm处的尖锐发射峰实现的,所述宽发射带是由于V5+−O2−电荷转移态跃迁,所述尖锐发射峰归属于Sm 3+离子的4G 5/2→ 6 HJ(J = 5/2、7/2、9/2、11/2)跃迁。通过调节Sm ~(3+)的掺杂浓度,可以实现发光颜色从绿色到白色的调谐。当Sm 3+的掺杂浓度从x = 0增加到x = 0.20时,Ca 2NaMg 2 V3 O 12:xSm 3+荧光粉的显色指数从55增加到83。本发明的白色磷光体显示出用于白色LED的巨大潜力。
Novel single-phased phosphors Ca2NaMg2-V3O12:xSm3+ that exhibit efficient white-light photoluminescence properties have been successfully synthesized by the solid-state reaction method. The formation of a single Ca2NaMg2V3O12 phase has been confirmed by X-ray powder diffraction (XRD). The wavelength-tunable white light is realized by coupling of the broad emission band at 500 nm due to a V5+−O2− charge-transfer state transition and the sharp emission peaks at 564, 616, 650 and 708 nm assigned to 4G5/2→6HJ (J = 5/2, 7/2, 9/2, 11/2) transitions of the Sm3+ ion. The luminescence color can be tuned from green to white by adjusting the doping concentration of Sm3+. When the doping concentration of Sm3+is increased from x = 0 to x = 0.20, the color rendering index of the Ca2NaMg2V3O12:xSm3+ phosphors increased from 55 to 83. The present white phosphors show a great potential for white LEDs.
