Aao Template Prepared Fluorescent Polymer One-dimensional Array Structure

One-dimensional nanomaterial was concerned since the carbon nanotube(CNT) was discovered. The nanomaterial of polymer is an important part of the nanomaterials, it is becoming a hot point of nanotechnology filed. The rare-earth metal is important luminescent material, the earth complexes and doped polymer were applied in different territory. If the luminous complexes were doped polymer to made composite nanoarrays, these researchs will be a interesting work.In this thesis, the ternary complexes of europium and terbium were synthetized by coprecipitation method. The structure and function of complexes were characterized, such as infrared spectroscopy(IR), ultraviolet spectrum(UV), thermogravimetric analysis(TG) and fluorescence spectrum. The complexes were doped in the solution of polymer(PS,PMMA,PVC) and made composite film by solution cast method. The composite membrane have higher thermal stability and optical property, the properties of complexes were not affected by the polymer.The ternary complexes were doped in the solution of polymer, the composite polymer nanoarrays were successfully fabricated by the multiwetting mechanism in a porous anodic aluminum oxide template(AAO), such as composite PS,PMMA,PVC nanoarrays. The as-prepared polymer arrays were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy dispersive spectroscopy(EDS) and fluorescent spectroscopy. It was found that the composite nanotube arrays were regular and their fluorescence intensity were enhanced in contrast with the pure complexes and composite bulk film. TEM images showed that the organometallic complexes were embedded in the nanowire and nanotube. Fluorescence excitation spectrum showed that the maximum inspire peak of nanoarrays move to high frequency direction. In addition, the above phenomenons were explained preliminary in this thesis.
