摘要：

Long afterglow strontium aluminates SrAl(4)o(7): Eu2+, Dy3+, Gd3+ phosphor was prepared by combustion method. The X-ray diffraction (XRD), Scanning electron microscope (SEM) and photoluminescence (PE) spectrum as well as the luminescence decay were used to characterize the long lasting phosphor. The emission, spectrum of the phosphor shows broadened band at 495 nm assigned to the 4f(6)5d -> 4f(7) (S-8(7/2)) transition of Eu2+. The present phosphor shows green persistent luminescence after removal of the UV light.
