摘要:

以多孔氧化铝为模板,通过水热反应制备出ZnS 和 C60纳米线阵列,分别用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、X射线衍射(XRD)、拉曼光谱以及选区电子衍射图谱(SAED)等,对纳米线阵列形貌和化学成分进行表征.结果表明,ZnS 和C60纳米线均为有序阵列.ZnS纳米线为多晶结构,在波长332 nm紫外光激发下, 发射519 nm特征荧光.同时介绍了水热条件下,在多孔氧化铝模板中填充目的产物,以及制备纳米线有序阵列的相关过程.该方法具有一定的普适性.

Abstract:

ZnS and C60 nanowire arrays were fabricated with a hydrothermal method using porous aluminum oxide membrane as templates in a tank of pressure at certain temperature. Images of ZnS and C60 nanowires are obtained by transmission electron microscope (TEM) and scanning electron microscope (SEM) respectively. X-ray diffraction (XRD), Raman spectrum and selected area electron diffraction (SAED) are employed to study morphology and chemical composition of the nanowires. The results indicate that all ZnS and C60 nanowires have ordered nano-array structure, and ZnS has a polycrystalline structure. Fluorescence spectroscopy was determined by 332 nm UV-light, and had a special fluorescence property with a strong characteristic emission appearing at 519 nm. The action mechanism of alumina template on the growing and its application prospects are investigated. 
