In　this　study,　a　series　of　broadband　emitting　yellow　phosphors　Sr8MgAl(PO4)(7):xEu(2+)　(SMAP:xEu(2+))　were　synthesized　by　high　temperature　solid.state　reaction;　and　the　structure,　luminescent　properties　and　potential　applica.　tion　in　white　light.　emitting　diode　(WLED)　were　investigated.　The　X.　ray　diffraction　(XRD)　results　showed　that　the　SMAP:xE(u2)+　phosphors　had　monoclinic　system　and　C2/m　space　group;　and　the　activator　Eu2+　ions　can　enter　into　the　SMAP　matrix　and　occupy　the　lattice　site　of　Sr2+　ions.　Diffuse　reflectance　spectroscopy　showed　that　SMAP　host　was　a　wide　band.　gap　material　with　a　band　gap　of　3.60　eV.　In　addition,　SMAP:xEu(2+)　had　a　broad　excitation　range　(280　similar　to　500　nm),　corresponding　to　the　4f(7)-＞　4f(6)5d(1)　transition　of　Eu2+　ions.　Under　the　excitation　of　380　nm　near.　ultraviolet　light,　there　was　an　asymmetric　yellow　emission　at　the　wavelength　of　450　similar　to　800　nm　from　multiple　emission　centers;　and　the　emission　peak　was　located　at　590　nm.　Based　on　Gaussian　multi.peak　fitting　results,　three　emission　centers　were　located　at　528,　600　and　680　nm,　respectively.　Finally,　the　as.　prepared　yellow　phosphor　SMAP:0.05Eu(2+)　and　commercial　blue　phosphor　BaMgAl10O17:Eu2+　were　mixed　and　coated　on　the　surface　of　400　nm　chip　to　fabricate　WLED　with　good　color　temperature　(3　344　K)　and　high　color　rendering　index　(90.1).
