Abstract: A novel highly water-resistant and organic miscible luminescent phosphor has been synthesized by grafting a polymer onto the surface of SrAl(2)O(4):Eu(2+), Dy(3+) (SAO-ED). A bifunctional ligand, 3-allyl-2, 4-pentanedione (APD) was used as a bridge to introduce the polymer onto the surface of SAO-ED. The coordination of APD with SAO-ED was confirmed by FT-IR spectra. The luminescence property of SAO-ED/polymer composite material was analyzed by spectrometer LS-100. The water resistance and miscibility with organics of the product were also investigated. Compared with traditional inorganic SAO-ED, this novel polymer-grafted SAO-ED has higher brightness, much better water resistance and good miscibility with organic solvents and polymers.
