摘要
通过静电纺丝原位反应法、同轴静电纺丝法两种方法制备了Ag-Eu(TTA)3AA/PVP纳米纤维,用SEM、TEM和荧光光谱研究了纳米银和所得纤维的形貌以及复合纤维的荧光性能。结果表明,所得纤维的直径小于1000nm,纳米银颗粒的直径从几十至200nm;Eu(TTA)3AA在纤维中分散均匀;两种方法制备的Ag-Eu(TTA)3AA/PVP纳米纤维中都存在着纳米银的荧光增强作用。
Ag nanoparticle - Eu （ TTA ） 3 AA/PVP [ TTA = 4,4,4- trifluoro-1 - （ 2-thienyl ） -1,3-butanedione ; PVP = poly （ vinyl pyrrolidone） ] single or coaxial nanofibers have been fabricated by electrospinning or coaxial electrospinning, respectively. SEM and TEM micrographs confirmed that Ag nanoparticles were present. The diameters of the nanofibers were less than 1000 nm and the diameters of the Ag nanoparticles were no more than 200 nm. Fluores cence enhancment was observed in both kinds of nanofiber.
