Abstract

Two types of bimetallic nanoparticle are constructed on soft substrates via a laser-induced transfer technique. One particle is a physical mixture with distinct gold and silver nanoparticles, while the other is a gold-silver alloy nanoparticle. Different hybrid plasmon responses can be achieved by these nanoparticles, which can be attributed to electromagnetic interactions between gold and silver. Both nanostructures can be fabricated using one or two ultraviolet laser pulses. Also, the stability of the spectra of these nanoparticles remains robust when the substrate is stretched and bended. These particles may provide an alternative way to investigate plasmonic sensors and random laser devices.
