Abstract:

金纳米双锥与金纳米棒颗粒因其自身的各向异性在红外谱段均呈现出显著的纵向表面等离激元共振特性。本文利用时域有限差分方法数值研究了金纳米双锥与金纳米棒的纵向表面等离激元共振特性，并对两者在纵向表面等离激元的可调谐性以及局域电场增强方面进行了比较。研究结果表明，相比于金纳米棒结构，金纳米双锥不仅在纵向表面等离激元共振峰的调控效率及波段调控范围上具有优势，而且还具有局域化程度更高、增强特性更为显著的电场分布。这一结果将对金纳米双锥与金纳米棒颗粒在光学传感、表面增强拉曼及光热转换治疗等领域的应用起指导作用。
Both the gold nanobipyramid and the gold nanorod exhibit significant longitudinal surface plas-mon resonance characteristics in the infrared spectrum due to their anisotropy. In this paper, the finite-difference time-domain method is used to numerically study the longitudinal surface plasmon resonance characteristics of gold nanobipyramid and gold nanorod structures and further compare the tunability of longitudinal surface plasmon resonance and local field enhancement. The results show that compared with gold nanorod structures, gold nanobipyramid have greater tunability of longitudinal surface plasmon resonance and stronger local field enhancements, which will be beneficial to gold nanobipyramid and gold nanorod application in optical sensing, surface-enhanced Raman scattering and infrared photothermal treatment.
