Metamaterial engineering of plasmonic metal luminescence
Metamaterial engineering of plasmonic metal luminescence
While metamaterials research has been focused on engineering the electric, magnetic and nonlinear responses of periodic sub-wavelength metallic structures, we show for the first time that metamaterial structuring can also be used to engineer the luminescent properties of this metal framework.
We demonstrate this experimentally by creating new luminescent bands in metallic gold. While the natural luminescence spectrum of bulk gold is dominated by a peak at about 516 nm resulting from the Fermi level to d-band transition, nanostructuring can create new, intense luminescent lines at frequencies anywhere below the natural band.
The wavelength of the new artificial emission line is linked to the plasmonic mode of metamaterial and its wavelength scales with the metamaterial's unit cell size. Using optical excitation at 400 nm we observed resonant emission in the range from 640 to 710 nm, controlled by scaling the nanostructure. Similar luminescent bands were observed in cathodoluminescence experiments

Abstract
While metamaterials research has been focused on engineering the electric, magnetic and nonlinear responses of periodic sub-wavelength metallic structures, we show for the first time that metamaterial structuring can also be used to engineer the luminescent properties of this metal framework.
We demonstrate this experimentally by creating new luminescent bands in metallic gold. While the natural luminescence spectrum of bulk gold is dominated by a peak at about 516 nm resulting from the Fermi level to d-band transition, nanostructuring can create new, intense luminescent lines at frequencies anywhere below the natural band.
The wavelength of the new artificial emission line is linked to the plasmonic mode of metamaterial and its wavelength scales with the metamaterial's unit cell size. Using optical excitation at 400 nm we observed resonant emission in the range from 640 to 710 nm, controlled by scaling the nanostructure. Similar luminescent bands were observed in cathodoluminescence experiments
