偕胺肟-Dy(Ⅲ)稀土配合物纤维的制备及荧光性能研究

Preparation and Function of Chelating Complex Fiber Containing Amidoxime Group-Dysprosium(Ⅲ)

以偕胺肟纤维(AOCF)和稀土Dy(Ⅲ)离子为原料,进行配位反应,制备了偕胺肟-Dy(Ⅲ)稀土配合物纤维。探讨了在不同的反应时间下,配合物中稀土Dy(Ⅲ)离子含量的变化;对其形貌进行了SEM观察,采用了红外光谱、XPS分析对其结构进行了表征;对配合物进行了荧光测试,研究了其荧光性能。结果表明:配合物纤维的形貌变得粗糙;随着反应时间的变化,AOCF与Dy(Ⅲ)配位逐渐达到饱和,配合物吸收峰发生了位移,电子结合能也发生了改变;在一定的激发波长下,纤维表现出良好的荧光性能。

Amidoxime-Dy（Ⅲ） coordination complex fiber was prepared by coordination reaction with AOCF andDy（Ⅲ） as raw material. Dy（Ⅲ） content in Amidoxime-Dy（Ⅲ） coordination complex fiber was investigated atdifferent reaction time. Many characterization methods such as SEM, IR and XPS were also used to testified onamidoxime-Dy （Ⅲ） coordination complex fiber. The results showed that coordination complex fiber become rough.With the increase of the coordination reaction time, coordination reaction between amidoxime and Dy （Ⅲ） becomesaturable. Absorption peak and electron binding energy of amidoxime-Dy （Ⅲ） coordination complex fiber werechanged. Atproperty.one kind of exciting wavelength, amidoxime-Dy（Ⅲ）coordination complex fiber has good fluorescence
