Eu2+doped　Sr2Al2SiO7luminescent　materials　were　prepared　by　sol-gel-combustion　reduction　method　under　the　condition　that　the　reaction　temperature　is　1100　and　the　pH　is　3　to　4.　The　crystal　structure　and　the　luminescent　properties　of　the　samples　were　characterized　and　measured　by　using　the　method　of　TG-DTA,　XRD　and　fluorescence　analysis.,　respectively.　The　results　showed　that　Sr2Al2SiO7:　Eu2+luminescence　materials　exhibited　tetragonal　system　crystal　structure,　and　its　excitation　spectra　was　a　broadband　spectrum　located　at　344　and　350　nm.　The　emission　spectrum　is　located　at　455　nm,　the　maximum　luminous　intensity　is　7500　mcd;　The　Eu2+doped　concentration　had　large　effects　on　luminescent　properties　of　the　prepared　material.　The　intensity　of　excitation　and　emission　spectrum　arrived　at　the　maximum　when　doped　molar　concentration　was　0.04.　©　2015,　Editorial　Office　of　＇Chinese　Rare　Earths＇.　All　right　reserved.
