Metal nanoshells

The metal shell has two surfaces, an inner one and an outer one, each with its own plasmon mode. These two plasmon modes couple across the thickness of the shell. The strength of the coupling is therefore determined by the field decay across the thickness (as 1/t assuming dipolar behavior) and the core polarizability, which is proportional to R, resulting in a similar size-scaling as in the two- [Pg.284]

Among metallic nanoparticles which have recently attracted considerable attention, a particularly interesting structure is the metallic nanoshell which consists of a metallic layer grown over a solid dielectric core [34,57,68-76]. [Pg.161]

It must be mentioned that a plasmon hybridization model was first developed by Nordlander and Halas in order to explain the LSPR resonances properties of metal nanoshell structures [48]. In a later section, we shall show the analogy between the hybridization in the two-particle dimer with that of a metal nanoshell. [Pg.277]

Extension of Photocatalytic Reduction Method, and the Post Chemical Reduction Treatment to Form Metal Nanoshell Structure... [Pg.165]

Perhaps, it becomes difficult to deposit gold (Au) NPs directly, as Au shell, on the surface of poly(DCHD) core by means of the photocatalytic reduction method [60], since the redox potential of [AuCU] , precusor of Au, is 1.002 mV vs SHE. This value is close to the redox potential of water given by (2) as well as VB for PDA as shown in Fig. 12. In addition, [AuC ] may absorb some VIS light, which is also undesirable in the present preparation procedure. However, already-deposited Ag NPs on poly(DCHD) core can be regarded as both a catalyst and a substrate for electroless plating with other kinds of metals. Thus, we could prepare metal nanoshell structure by means of post-chemical reduction treatment. [Pg.167]
