摘要
Longlastingstrontiumaluminatephosphorsweresynthesizedbymeansofcoatedprecipitationintheexperiment.SrA12O4monoclinicphasewithlongafterglowwassynthesizedat1100℃withtheaidofH3BO3,andthesynthetictemperaturedecreasedabout100℃-150℃thaninsolidstatereaction.TheprocessofheattreatmentwasstudiedbyTG-DTA.ThephasecompositionsofpowderswereanalyzedbyXRD.ThemicrographsofthesampleswereinvestigatedbySEMandtheluminescentpropertieswereresearchedbyopticalspectrum.TheeffectsofH3BO3onthephasecompositionandmicrostructureofthecalcinedpowderswereinvestigated.TheresultsindicatedthatH3BO3acceleratedtheformationofSrAl2O4byconsumingtheintermediatephase.TheadditionofDy2O3stimulatedtheafterglowpropertyduetotheincreaseinthedepthofthetrapcenterinthematerials.
