Journal ArticleDOI
The Optimal Aspect Ratio of Gold Nanorods for Plasmonic Bio-sensing
TL;DR: In this paper, the authors use simulations based on the boundary element method to determine the sensitivity of gold nanorods of various aspect ratios for plasmonic sensors and find values between 3 and 4 to be optimal.
Journal ArticleDOI
Plasmonic focusing reduces ensemble linewidth of silver-coated gold nanorods.
TL;DR: Silver coating gold nanorods reduces the ensemble plasmon line width by changing the relation connecting particle shape and plAsmon resonance wavelength, which leads to less variation of resonance wavelengths for the same particle size distribution.
Journal ArticleDOI
Highly sensitive plasmonic silver nanorods.

TL;DR: Using the Drude-model of optical properties of metals together with the quasi-static approximation for localized surface plasmons, it is shown that the dominant contribution to higher sensitivity of silver is the lower background polarizability of the d-band electrons.
Journal ArticleDOI
Light-controlled one-sided growth of large plasmonic gold domains on quantum rods observed on the single particle level.
TL;DR: Large gold domains eventually form; these support efficient plasmon oscillations with a light scattering cross section large enough to visualize single hybrid particles in a dark-field microscope during growth in real time.
Journal ArticleDOI
Tuning Plasmonic Properties by Alloying Copper into Gold Nanorods
TL;DR: In this article, a rod-shaped single crystalline gold−copper (AuxCu(1-x)) nanoparticles were created and verified the presence of copper in the particles with various direct and indirect optical and electron microscopy techniques.
