Abstract–Numerical calculations and a comparative analysis of light extinction spectra of single silver nanoparticles shaped as sphere, rod, dumbbell, disk, and triangular prism are performed using the FDTD method. The strong dependence of the results for intensities and positions of maxima of localized plasmon resonance peaks on the geometrical shape of particles.

不同几何形状的等离子体纳米粒子的光谱比较分析

摘要–使用FDTD方法对球形，棒状，哑铃形，圆盘状和三角形棱柱形的单个银纳米粒子的消光光谱进行了数值计算和比较分析。结果强烈依赖于局部等离振子共振峰的强度和位置对颗粒几何形状的依赖。
