| 摘要: 采用热蒸发法在SiO2自组装单层膜上制备了帽状锑纳米粒子，通过扫描电镜(SEM)、原子力显微镜(AFM)、X射线衍射仪(XRD)和紫外-可见-近红外(UV-Vis-NIR)分光光度计对帽状复合纳米粒子的表面形貌、结构以及表面等离子共振特性进行了研究和表征。结果表明，制备的复合纳米粒子呈帽状，表面等离子共振峰具有明显的可调谐性，当二氧化硅粒径增大或锑帽层厚度增加时，等离子共振吸收峰位置红移。 |

| Abstract: Cap-shaped Sb nanoparticles were prepared by evaporating Sb on the self-assembled monolayer arrays of SiO2 nanoparticles. The surface morphologies, structure and surface plasmonic resonance of composite nanoparticles were characterized using scanning electron microscopy(SEM), atomic force microscopy(AFM), X-ray diffraction(XRD) and UV-Vis-NIR spectroscopy. The results show that the composite nanoparticles are cap-shaped and the plasmonic absorption peaks are moved to near-infrared region with increasing SiO2 diameter and Sb cap thickness. |
