中文摘要:
      以钐离子为中心体,利用二苯甲酰基甲烷(DBM)为第一配体,1,10-菲啰啉(phen)为第二配体与氯化钐在乙醇中反应,加入Gd3+对其敏化,合成了具有发光性能的稀土钐三元配合物Sm/Gd(DBM)3phen。将钐三元配合物与聚丙烯酰胺(PAM)进行共聚反应,制备了一种键合型稀土聚丙烯酰胺共聚物。通过元素分析、傅里叶变换红外光谱、紫外光谱、荧光光谱分析、热重分析测定了配合物及共聚物的组成、结构、发光性能及稳定性,结果表明,Sm/Gd (DBM)3phen/PAM的发光性能优于Sm/Gd(DBM)3phen,在紫外光的激发下于559、597、643 nm处发射出Sm3+的4G5/2—6H5/2、4G5/2—6H7/2、4G5/2—6H9/2[正斜体,全文保持一致]跃迁的特征荧光。其中,不发光的Gd3+对于发光的Sm3+的荧光强度有很明显的增强作用。
英文摘要:
      A luminous ternary complex Sm/Gd(DBM)3phen was synthesized by coordination of samarium using dibenzoyl methane(DBM) as the first liand, 1, 10-phenanthroline(phen) as the second ligand and samarium chloride reaction in the ethanol.A bonded rare earth polyacrylamide copolymer was prepared by copolymerization of the samarium ternary complex with polyacrelamide (PAM). The composition, structure, fluorescence properties and stability of complex and copolymer were characterized by means of elemental analysis, Fourier transform infrared spectroscopy, UV spectroscopy, fluorescence spectroscopy and thermogravimetric analysis, the research results show that the Sm/Gd(DBM)3phen/PAM luminescence performance is better than that of Sm/Gd(DBM)3 phen, the characteristic luminescence of samarium ion 4G5/2—6H5/2, 4G5/2—6H7/2, 4G5/2—6H9/2 at 559,597,643 nm is excited by UV light. The non-luminescent Gd3+ has a significant enhancement on the fluorescence intensity of luminescent Sm3+.
