摘　　要：合成了一种共聚型低聚物的新型三元复合物Eu3+-AAO-TTA（AAO:低聚丙烯酰胺丙烯酸，n（丙烯酰胺）/n（丙烯酸）=7∶3，数均相对分子质量为10000; TTA：荧光敏化剂2噻吩甲酰三氟丙酮）并测定了其荧光光谱.三元复合物的荧光强度是二元复合物Eu3+AAO荧光强度的21倍，并且比强发光物质NaEu(TTA)4的荧光强度更强.研究了pH值、Eu3+低聚物物质的量比、Eu3+-TTA物质的量比对复合物荧光强度的影响.所得三元复合物具有作为优良发光材料的应用前景.A novel ternary composite of Eu3+-AAO-TTA (AAO: oligomer of n(acrylamide)/n(acrylic acid)=7∶3, Mn=10000; TTA: 2-thenoyltrifluoroacetone) is synthesized and its luminescence spectrum is measured. The luminescent intensity is twenty times larger than that of Eu3+ AAO binary composite and even greater than that of NaEu(TTA)4, a strong light emitter. The influences of pH and molar ratios of n (Eu3+)∶n(AAO) and n(Eu3+)∶n(TTA) on luminescent intensities are investigated. As a luminescent material, the composite has good prospect in application.
