Spectra of light extinction by metal nanoprisms and nanostars coated with molecular aggregates of organic dyes are calculated and theoretically analyzed. Qualitatively different nature of the spectra of organometallic nanoparticles under study is established when using J-aggregates of various cyanine dyes as their capping layer, as well as silver and gold as the cores. This results from the implementation of various plasmon-exciton coupling modes in the systems under consideration.

双层有机金属纳米片的消光光谱

计算并理论分析了金属纳米棱镜和涂有有机染料分子聚集体的纳米星的消光光谱。当使用各种花青染料的J聚集体作为其覆盖层时，以银和金为核，可以确定所研究的有机金属纳米颗粒的光谱在质上有不同的性质。这是由于在所考虑的系统中实现了各种等离激子-激子耦合模式。
