The Invention provides a long after-glowing phosphor, with a polymer is grafted, which is composed of a Alkaline earth aluminate-phosphor, which with a polymer by coordination bond has been grafted, and a method for producing the same, ready. The method for the preparation of the grafted with a polymer Phosphor comprises two steps : The alkaline earth aluminate, which by rare earth metal ion has been activated is with a difunctional ligand coordinated, for coordinated a long after-glowing to form phosphor; the coordinated long after-glowing Phosphor was in an organic solvent at a temperature from 40 to 130 °C dispersed, the ligand was initiated by an initiator and could copolymerize with other polymerizable monomers, to target the polymer-grafted long after-glowing phosphor to form. The formed a good water resistance have phosphors and good luminescence properties. You can, in many cases, are used in areas of luminescence coatings , paints and plastics.
