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。

关 键 词:帽状锑纳米粒子    复合纳米粒子    表面等离子共振

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.
Keywords:cap-shaped Sb nanoparticles  composite nanoparticles  surface plasmonic resonance
