| 摘 要： | 采用溶胶-凝胶法成功地制备出一种椭球形核-壳结构二氧化硅包覆的金纳米棒.分别采用透射电镜、扫描电镜、紫外、电子衍射和扫描电镜能谱对制备出的二氧化硅包覆的金纳米棒进行表征.结果表明二氧化硅包覆的金纳米棒呈椭球形,大小为60～80nm,壳层二氧化硅厚度约10～20nm.通过紫外检测发现,二氧化硅壳层对金纳米棒的光学特性几乎没有影响.试验结果表明,这种新颖的二氧化硅包覆的金纳米棒微球在生物医学(如治疗、传感器和分子影像等)中有着潜在的应用价值. |

| Abstract: | The spherical core-shell silica-coated gold nanorods were successfully prepared by a sol-gel method.The obtained nanospheres were characterized by transmission electron microscopy,scanning electron microscopy,ultraviolet spectroscopy,selected area electron diffraction,scanning electron microscopy and energy-dispersive X-ray spectroscopy.The results indicated that the as-prepared nanospheres are approximate sphere with size about 60-80nm,the thickness of SiO2 is about 10-20nm.The plasmon peaks of silica-coat... |
