Multiphase gallium-based nanoparticles for a versatile plasmonic platform

Conference Paper

Gallium nanoparticles have been deposited on various substrates of technological interest. The interaction with the substrate leads to two plasmon resonance modes that can be tuned from the UV to the visible and infrared. Large polarization-dependent splitting of plasmon resonance modes arises from the broken symmetry of hemispherical gallium nanoparticles on substrates; this splitting depends on interaction with the substrate, on the angle of illumination and on the polarization state of light. These splitting plasmon modes are also dependent on the liquid and solid phases of gallium.
