Eu2+, Dy3+ co-doped alkaline earth aluminates MAl2O4: Eu2+, Dy3+ (M = Ba, Sr) have been prepared by in situ self-propagating high temperature synthesis (SHS) method. The influence of co-doping rare earth ions (Eu2+, Dy3+) on the luminescence of MAl2O4:Eu2+, Dy3+ were described in this study. The particles morphology, photoluminescence and afterglow properties of the phosphors were studied. Broad band UV excited luminescence was observed for BaAl2O4:Eu2+, Dy3+ and SrAl2O4:Eu2+, Dy3+ in the green region peak at max = 503 nm and 523 nm, respectively. The dopant (Eu2+) and co-dopant (Dy3+) concentrations affect the crystallinity and luminescence properties of the materials.
