The spectra of localized surface plasmon resonances (LSPRs) in self-assembled silver nanoparticles (NPs), prepared by solid-state dewetting of thin films, are discussed in terms of their structural properties. We summarize the dependences of size and shape of NPs on the fabrication conditions with a proposed structural-phase diagram. It was found that the surface coverage distribution and the mean surface coverage (SC) size were the most appropriate statistical parameters to describe the correlation between the morphology and the optical properties of the nanostructures. The results are interpreted with theoretical predictions based on Mie theory. The broadband scattering efficiency of LSPRs in the nanostructures is discussed towards application as plasmon-enhanced back reflectors in thin-film solar cells.
我们讨论了通过薄膜固态去湿制备的自组装银纳米粒子（NPs）中局域表面等离子体共振（LSPR）的光谱，根据其结构特性进行了讨论。我们总结了 NPs 的尺寸和形状对制造条件的依赖性，并提出了一个结构相图。研究发现，表面覆盖率分布和平均表面覆盖率（SC）大小是描述纳米结构形态和光学特性之间相关性的最合适的统计参数。结果是基于 Mie 理论的理论预测进行解释的。我们还讨论了在纳米结构中 LSPR 的宽带散射效率，以期将其应用于薄膜太阳能电池中的等离子体增强后反射器。
