偕胺肟-稀土离子Tb(Ⅲ)、Dy(Ⅲ)配合物坯布的制备及荧光性能研究

Preparation of amidoxime-Tb(Ⅲ),Dy(Ⅲ) complex fiber and its fluorescent property

将腈纶(PAN)坯布与羟胺溶液反应,得偕胺肟腈纶坯布(AOCF),再将AOCF分别放入三氯化铽(TbCl3)、三氯化镝(DyCl3)溶液中,温度为45℃,pH=3,反应2.5h,分别制得偕胺肟腈纶坯布-铽离子配合物[AOCFTb(Ⅲ)]、偕胺肟腈纶坯布-镝离子配合物[AOCF-Dy(Ⅲ)]。对制得的坯布进行表征和荧光性能测试。研究结果表明:在紫外线激发波长为320nm时,AOCF-Tb(Ⅲ)的荧光发射波峰为468.5nm;在紫外线激发波长为300nm时,AOCF-Dy(Ⅲ)的荧光发射波峰为475.0nm。

The amidoxime fiber（AOCF）was prepared by reacting PAN in the hydroxylamine solution.Then,AOCF-Tb（Ⅲ）-PAN complex fibers,AOCF-Dy（Ⅲ）-PAN complex fibers were prepared by coordination reaction used AOCF and TbCl3,DyCl3,separately.The coordination reaction was carried out at 45℃ about 2.5 h with pH=3.The fluorescence emission peak of AOCF-Tb（Ⅲ）was at 468.5 nm when the ultraviolet excitation wavelength was 320 nm.And,when the ultraviolet excitation wavelength was 300 nm,the fluorescence emission peak of AOCF-Dy（Ⅲ）was at475.0 nm.
