Abstract

We report on experimental and theoretical studies of plasmon-induced effects in a hybrid nanostructure composed of light-harvesting complexes and metallic nanoparticles in the form of semicontinuous silver film. The results of continuous-wave and time-resolved spectroscopy indicate that absorption of the light-harvesting complexes is strongly enhanced upon coupling with the metallic film spaced by 25 nm of a dielectric silica layer. This conclusion is corroborated by modeling, which confirms the morphology of the silver island film.

摘要

我们报道了在一种由光捕获复合物和呈半连续银膜形式的金属纳米颗粒组成的混合纳米结构中，等离激元诱导效应的实验和理论研究。连续波和时间分辨光谱的结果表明，当与由25纳米介电二氧化硅层隔开的金属膜耦合时，光捕获复合物的吸收会显著增强。这一结论通过建模得到了证实，该模型确认了银岛膜的形态。
