Gold nanoshells, with a silica core and different core and shell dimensions, have been
extensively investigated. Optical far-field properties, namely extinction and absorption, have …

Gold nanoshells, nanoparticles consisting of a silica core coated with a thin gold shell,
exhibit a strong optical resonance that depends sensitively on their core radius and shell …

Most gold nanoparticles have surface plasmon fields only surrounding their surfaces.
Recently, hollow nanoparticles have been studied, such as gold nanocages (AuNC) and …

Tunable hollow Au/Ag nanospheres with an outer particle diameter of 55nm and extinction
maxima in the range of 600–700nm were synthesized. An increasing amount of gold in the …

We have synthesized a novel Au@ Au core–shell structure containing a spiky shell and
characterized the surface enhanced Raman spectroscopy (SERS) of such a structure. The …

A metal nanoshell is a composite nanoparticle consisting of a dielectric core coated by a thin
metal shell; its peak plasmon resonance wavelength is determined by the ratio of the core …

Gold nanoshells consist of a dielectric core surrounded by an ultra thin shell of gold. By
adjusting the ratio between the radius of the core and the thickness of the shell the plasmon …

Enhancements of the Raman signal by the newly prepared gold–palladium and gold–
platinum double-shell hollow nanoparticles were examined and compared with those using …

Surface-enhanced Raman scattering (SERS) activity of silver-gold bimetallic nanostructures
(a mean diameter of∼ 100 nm⁠) with hollow interiors was checked using p …

This paper presents a method for measuring the optical absorption cross sections (σa) of
Au− Ag nanocages and Au nanorods. The method is based on photoacoustic (PA) imaging …
