Abstract

The long afterglow phosphor CaAl2O4: Eu2+, Nd3+was prepared by combustion synthesis, and the influence of glycine on the luminescent properties of the long afterglow phosphor was studied. The samples were characterized by X-ray diffraction (XRD) and fluorescence spectroscopy (PL) etc. The results showed that the main phase of the combustion products is CaAl2O4with monoclinic crystal structure. The introduction of glycine prolongs the afterglow time.
