Abstract

The search for new materials for plasmonics and nanophotonics is justified by the need to create miniaturized optical nanodevices with unique properties in one nanostructure. High-entropy alloys have many material properties due to the peculiarity of the internal structure and multicomponent nature. These facts make such systems promising for nanophotonics. This paper presents the results of the experiments on the femtosecond laser ablation of a bulk material in an inert medium to create sphere-like nanoparticles of various sizes. Dark-field spectroscopy studies have demonstrated the presence of natural resonances in nanospheres, as well as their behavior with variation in the size of nanoparticles. We believe that the obtained results are perspective for creation of nanophotonic systems with extended functionality.
