The effects of substrates with technological interest for solar cell industry are examined on the plasmonic properties of Ag nanoparticles fabricated by dewetting technique. Both surface matching (boundary element) and propagator (finite difference time domain) methods are used in numerical simulations to describe plasmonic properties and to interpret experimental data. The uncertainty on the locations of nanoparticles by the substrate in experiment is explained by the simulations of various Ag nanoparticle configurations. The change in plasmon resonance due to the location of nanoparticles with respect to the substrate, interactions among them, their shapes, and sizes as well as dielectric properties of substrate are discussed theoretically and implications of these for the experiment are deliberated.
研究了具有太阳能电池工业技术意义的衬底对通过去湿技术制备的银纳米颗粒的等离子体特性的影响。在数值模拟中使用表面匹配（边界元）和传播子（时域有限差分）方法来描述等离子体特性并解释实验数据。通过各种银纳米颗粒配置的模拟解释了实验中衬底对纳米颗粒位置的不确定性。从理论上讨论了由于纳米颗粒相对于衬底的位置、它们之间的相互作用、它们的形状和尺寸以及衬底的介电特性导致的等离子体共振变化，并探讨了这些对实验的影响。
