关 键 词：Cyclodextrin Chelating agent Phosphor Grain size
摘 要：SrAlO:Eu,Dyluminescent phosphor was synthesized for the first time from using cyclodextrin as chelating agent by sol-gel *** structural characterization,surface morphology and properties of the phosphor were *** results revealed that the target phosphor with relatively regular morphology,smaller grain size,pure phase and high crystallinity can be achieved at 1200℃for4hin a reducing *** average grain size of the SrAlO:Eu,Dyphosphor nanoparticles ranges from 50 to 100 *** the phosphorescence in blue-green(483 nm)by Eu.
