摘　　要：以量子尺度下球形和棒形Ag纳米颗粒为研究对象,通过数值模拟的方法对其吸收散射特性进行建模分析。结果表明:修正模型的计算结果相对于经典模型而言,吸收峰的位置发生明显移动,且峰值明显减小。棒形结构Ag纳米颗粒的吸收峰可有效优化至可见光波段,且有较高的吸收因子值。In this paper,the research objects are the spherical and rod-shaped Ag nanoparticles at quantum scale.Their absorption and scattering properties are modelled and analyzed by numerical simulation.The results show that,compared with the calculated results of classical model,the absorption peak positions of the modified electromagnetic model have moved significantly,and the values of the peaks have been significantly reduced.The absorption peak of the rod-shaped Ag nanoparticles can be effectively optimized to the visible light band and a higher absorption factor value.
