We report on recent progress in the production and the deposition on surfaces of dielectric materials of self-assembled metallic nanoparticle systems able to organize into branched networks. We emphasize the interest of these new objects for tailoring novel near-field optical properties that could be the basis for optical energy transport in systems of extremely reduced sizes. The experimental optical spectra of such chain networks in solution can be very well reproduced by applying the coupled-dipole approximation scheme. In this paper, we apply this method to investigate the near-field optical properties of self-assembled plasmonic nanoparticle networks deposited on transparent surfaces.
我们报告了能够组织成分支网络的自组装金属纳米粒子系统在介电材料制备及其在表面沉积方面的最新进展。我们强调了这些新物体对于定制新型近场光学特性的意义，这些特性可能是超小尺寸系统中光能传输的基础。通过应用耦合偶极近似方案，可以很好地再现此类溶液中链状网络的实验光谱。在本文中，我们应用该方法来研究沉积在透明表面上的自组装等离子体纳米粒子网络的近场光学特性。
