Paper Abstract

SrAl2O4:Eu2+,Dy3+ was synthesized from various composition by high-temperature solid-state reaction and the effect of composition on the afterglow phosphorescence have been evaluated. The luminescent propertis were depended to a large extent on the calcination conditison and stoichiometry under which the phosphor is prepared. In order to study the luminscent character of the long-afterglow material, the whole decay curves of 10h were measured. The emission spectra and the excitation spectra of SrAl2O4:Eu3+,Dy3+ powders were shown, and the poweder x-ray diffraction pattern was obtained also.
