We investigate localized plasmon-mode resonances in the scattering and absorption of transversely polarized light by bimetal core–shell nanowires made of silver and gold, in two possible combinations, using an analytical solution and experimental data for metal permittivities. In particular, the influence of the metal shell thickness and material on these resonances is studied. We show that, unlike metal nanotubes with dielectric filling, bimetal wires do not display plasmon-mode hybridization.

核壳双金属纳米线的局部表面等离激元模式不杂交。

我们使用分析方法和金属介电常数的实验数据，研究了由银和金制成的双金属核-壳纳米线在两种可能的组合中对横向偏振光的散射和吸收中的局部等离振子模式共振。特别是，研究了金属壳厚度和材料对这些共振的影响。我们表明，与具有电介质填充的金属纳米管不同，双金属丝不显示等离激元模式杂交。
