荧光聚氯乙烯纳米线阵列的制备及研究

Fabrication of Fluorescence Polyvinyl Chloride Nanowire Arrays in Anodic Aluminum Oxide Template by the Multiwetting Mechanism

采用溶液浸润AAO模板法，将自制的荧光稀土配合物Eu（aspirin）3 Phen掺杂到聚氯乙烯（PVC）溶液中，制备了有荧光特性的一维复合纳米线阵列。并采用扫描电镜（SEM）、能谱分析（EDS）及透射电镜（TEM）进行了结构分析，结果表明：掺杂稀土铕配合物的聚氯乙烯制备了规整的纳米线阵列，铕配合物存在于纳米线阵列中。此外，荧光发射光谱研究表明，复合纳米线阵列具有优并的发光性能，归因于稀土配合物在纳米阵列中能更好地分散。

The ternary lanthanide complexes with good luninescent property Eu（aspirin）3 Phen was doped polyvinyl chloride. The fluorescent PVC nanowires were successfully fabricated by solution--wetting method in a porous anodie aluminum oxide membanc. The as--prepared PVC nanowire arrays were characterized by scanning electron microseopy, energy dispersive spectroscopy, transmission electron microscopy. It was found that the composite nanowire arrays were regular, the organometallic complexes embedded in the nanowire arrays. In addition, their fluorescence emission spectrum was studied. The fluorescence intensity of nanowire arrays were excellent because the composite nanowire arrays could provide a excellent dispersion of environment for lanthanide complexes.
