Photoluminescent Properties of Tungstoeuropium Heteropoly Acid/Polyacrylamide Materials

Tungstoeuropium heteropoly acid Na₉EuW₁₀O₃₆·32H₂O was synthesized and the polyacrylamide flim materials contained heteropoly acid were prepared by aqueous solution polymerization.IR sprctra of the polyacrylamide flim materials indicated that Keggin structure of Na₉EuW₁₀O₃₆·32H₂O still retain.FS sprctra indicated the polyacrylamide with heteropoly acid can emit characteristic luminescence of Eu³⁺ ion.Moreover,it showed strong luminescent properties after sensitization of miltioxygen metal cluster.
