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。
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 film materials indicated that Keggin structure of Na9 [ EuW10O36] ·32H2O still retain. FS sprctra indicated the polyacrylamide with heteropoly acid can emit characteristic luminescence of Eu^3＋ ion. Moreover, it showed strong luminescent properties after sensitization of mihioxygen metal cluster.
