In this research, a simple method of fabricating randomly distributed, core-shell-like plasmonic nanoparticles is presented. A modified nanosphere lithography method was used to create non-periodic arrays of nanoholes filled with metal-capped dielectric spheres. This approach is very quick, cost-effective and allows for the nanostructurization of multiple substrates at the same time. In this study, the influence of geometrical and material properties of the plasmonic response, SERS enhancement factor and uniformity of Raman signal of such structures was investigated. The optimization of the structures was carried out theoretically by means of FDTD calculations and then confirmed experimentally.
