Hybrid assemblies of nanoparticles made from different materials are intriguing systems for the reason that the combined properties of a hybrid structure can often outperform the properties of its individual components. However, the exact positioning of the individual particles in a dimer configuration right next to each other is challenging and usually requires high-end nanofabrication methods such as scanning probe or eBeam lithography.
Here, we introduce an all-optical approach for the precise patterning of dimer structures of both plasmonic and non-metallic nanoparticles. First, we will demonstrate how individual gold particles can be optically printed on glass by optical force [1] and illustrate strategies to apply this method for the fabrication of plasmonic nanoantennas. Second, we will show how both, metallic and non-metallic nanoparticles, can be patterned in a dimer configuration with a precision of a few nanometers by taking advantage of plasmonic heating and near-field effects.
