SBA-15模板法合成硫化锌纳米束及其光电性能
Preparation of ZnS Nanobundles by SBA-15 Template and Their Photoelectric Properties
摘要
Abstract
Highly ordered ZnS nanobundles were prepared using SBA-15 as a template and zinc ethyl xanthate as a single precursor. The nanobundles were characterized by transmission electron microscopy (TEM), thermal gravimetriedifferential thermal analysis (TG-DTA), X-ray diffraction (XRD), N2 adsorption-desorption, ultraviolet-visible (UV-Vis)spectroscopy, fluorescence spectroscopy, and scanning electron microscopy (SEM). Results showed that ZnS nanobundles possessed a highly ordered hexagonal mesostructure and fiber-like morphology, analogous to the mother template. One of the ZnS nanobundles was aligned by an alternative current (AC) electric field assembly and the rectification performance for one of the ZnS nanobundles was characterized by a semiconductor characteristic measurement system. Results demonstrated that under UV illumination, the current-voltage (Ⅰ-Ⅴ) characteristics of ZnS nanobundles could be changed significantly and a ZnS nanobundle photoelectric switching effect was observed. The mechanism of the rectifying behavior and the photoelectric switching effect of the ZnS nanobundles are discussed.关键词
