摘要: 合成了钨铕杂多酸,并与丙烯酰胺单体通过水溶液聚合制备了钨铕杂多酸/聚丙烯酰胺薄膜材料(EuW10/PAM)。红外光谱表明EuW10/PAM聚合物膜中的钨铕杂多酸仍保持Keggin结构;荧光分析表明,EuW10/PAM呈现典型的Eu3+离子的特征荧光,而且经过多氧金属簇的敏化,呈现强的荧光性能。Abstract: Tungstoeuropium heteropoly acid [Na9[EuW10O36]·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 Na9[EuW10O36·32H2O 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.
