摘要

计算了粗糙纳米线和圆柱形纳米线之间含银纳米粒子结构的光谱。采用时域有限差分法(FDTD)进行仿真。作为辐射源，使用波长范围为300 - 1000nm的平面波。结果表明，随着粗糙纳米线RMS粗糙度的增加，在500 ~ 750 nm范围内，由于反射效应的增加，吸收系数减小。当加入银纳米粒子时，在840 nm(圆柱形纳米线)和900 nm(粗糙纳米线)的波长处出现峰，表明表面等离子体共振效应的表现。结果表明，粗糙纳米线体系的电场强度高于圆柱形纳米线体系。

Modelling the optical characteristics of cylindrical and rough nanowires with silver nanoparticles

The optical spectra of structures with Ag nanoparticles between rough and cylindrical nanowires are calculated. The simulation was carried out using the finite-difference time-domain method (FDTD). As a source of radiation, a plane wave with the range of wavelengths 300–1000 nm is used. It is shown that with an increase in the root mean square (RMS) roughness of rough nanowires, the absorption coefficient decreases in the range of 500–750 nm due to an increase in the reflection effect. When silver nanoparticles are added, peaks appear at the wavelength of 840 nm (for cylindrical nanowires) and 900 nm (for rough nanowires), which indicates the manifestation of the surface plasmon resonance effect. It is shown that the electric field strength in a system with rough nanowires is higher than in a system with cylindrical nanowires.
