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. |
