英文摘要	The crystal structure of Sr8CaSc(PO4)(7): Eu2+, Ce3+, Mn2+ phosphor was refined and determined from Rietveld refinement method. The occupation for Eu2+, Ce3+ at Ca2+ ion site and Mn2+ at Sc-3+ site in Sr8CaSc(PO4)(7) host material were proved by the XRDs profiles and Van Uitert equation. The designed trienergy transfer process of Eu2+ -> Mn2+ , Ce3+ -> Mn2+ and Ce3+ -> Eu2+ -> Mn2+ occurred in Sr8CaSc(PO4)(7) phosphor, and furtherly certified by their decay curves. The corresponding calculated energy transfer efficiencies indicated that the energy transfer Ce3+-> Mn2+ made the main contribution on the emission enhancement of Mn2+ ion. The chromaticity and color temperature of Sr8CaSc(PO4)(7): xEu(2+), yCe(3+), zMn(2+) phosphors were conveniently adjusted in a broad region by the tri-energy transfer and different excitation energy, which is from (0.2914, 0.3396), 7606 K to (0.4458, 0.3303), 2013 K under 311 nm excitation and (0.2248, 0.5466), 8000 K to (0.3978, 0.4932), 4231 K under 370 nm excitation, respectively. Meanwhile, the corresponding quantum efficiency was improved up to 36.3% in Sr8CaSc(PO4)(7): 1% Eu2+, 2.5% Ce3+, 2% Mn2+ phosphor by tri-energy transfer and high excitation energy 311 nm. The corresponding fabricated 310 SCSPO-LED and 370 SCSPO-LED showed the chromaticity and color temperature as (0.241, 0.345), 10818 K and (0.339, 0.254), 4673 K respectively, that prove Sr8CaSc(PO4)(7): xEu(2+), yCe(3+), zMn(2+) phosphors have potential application value on NUV WLEDs.
