摘要： 利用多孔氧化铝作模板采用熔融法成功制备了一种定向有序排列的有机小分子(NPB)纳米管,并用场发射扫描电镜(FESEM)、X射线能量损失谱(EDX)、透射电子显微镜(TEM)和荧光显微镜对其进行了表征.发现该纳米管具有整齐的形貌和规整的尺寸.进一步的研究表明,多孔氧化铝模板的亲油亲水处理对能否成功地大量获得纳米管起到非常重要的作用.值得注意的是,在对不同尺寸纳米管材荧光光谱的测定中,可明确观察到材料光学性质的尺寸依赖性.

Abstract: Aligned nanotubes of organic electroluminescent material(NPB) were prepared by a simple melting method with an anodic aluminum oxide(AAO) membrane as the template. The nanotubes arrays obtained were characterized by means of scanning electron microscope(SEM), energy dispersive X-ray(EDX) analyzer, transmission electron microscope(TEM) and fluorescence microscope, respectively. The prepared nanotubes possessed a uniform shape and regular size. Further investigation indicated that the surface modification of the templates played an important role in the process of preparation. It was also worth mentioning that the nanotubes with different sizes exhibited a very interesting size-dependent photo-luminescence(PL) behavior.

Key words: N,N-Bis(α-naphthylphenyl)-4,4'-biphenyldiamine(NPB), Nanotube, Porous anodic aluminum oxide(AAO) template, Size-dependence of photo-luminescence(PL)
