Abstract: BaMgAl10O17: Eu2+ phosphors was prepared by the solid-reaction method.Y2SiO5 was coated uniformly on the surface of phosphor by the surface-coated method, and the luminescent and deterioration properties were discussed.The XRD and SEM results show that Y2SiO5 film is produced on the surface of BAM phosphor.The emission spectrum analysis shows that the peak of the phosphor does not change after coating.The two phosphors were applied to lamps and the deterioration was tested at different ignited time.The keep ratio of luminous flux of the phosphor coated with Y2SiO5 is higher than that of the uncoated phosphor.
