Lange more after-glowing activated alkaline earth aluminate-phosphor with rare earth metal ion, with a polymer is grafted by coordination bond, characterized in that the phosphor is the product of a polymerization of an organic monomer on the surface of a rare earth metal ion is activated particulate alkaline earth metal aluminate with, the is coordinated with a ligand, which has the following formula : (B) n A (1) where A is a rare earth metal ion is activated alkaline earth aluminate-phosphor with is coordinated with a difunctional ligand, which is the product of the co-ordinate bonding between the activated alkaline earth aluminate and the difunctional ligand with rare earth metal ion, wherein the rare earth metal ion comprise alkaline-earth aluminates the experimental formula with activated : M x Aly Oz : Eu 2 +, E (2), wherein at least one alkaline earth metal ion selected from the group consisting of 2 Ca M +, 2 + mg, 2 + 2 + and Ba represents Sr; E at least one rare earth ion selected from the group consisting of Ce 3 +, 3 + Tb, Dy 3 +, 3 + 3 + and Pr represents Nd; x is an integer from 1 to 4 is; Y is an integer from 2 to 14 is; z is an...
