【摘要】 基于边界元理论对不同形状和大小的金纳米粒子进行了仿真和理论分析,通过在不同折射率的介质中得到的消光光谱,得出相应的灵敏度曲线.经过多次的拟合和理论分析,发现当金纳米圆柱环满足R/h是定值且r=R-h时,折射率灵敏度几乎不变这一规律,为金纳米圆柱环的制备提供了仿真的理论依据.更多还原

【Abstract】 Based on the theory of BEM gold nanoparticles of different shapes and sizes of the simulation and theoretical analysis, by extinction spectra of different refractive index medium obtained, draw the corresponding sensitivity curve. After many fits and theoretical analysis, found that when gold ring cylinder satisfies R/h is a fixed value and r=R-h, the sensitivity of the refractive index is almost unchanged this law, prepared gold ring cylinder to provide simulation of Theoretical basis.更多还原
