“…4(b) is that corresponding to a crossed rod target with =15º. The positions and origins of the transverse and longitudinal peaks on the sample with =0º (the simple rod) are consistent with previously reported results [37][38][39][40][41][42], with a transverse resonance at ~520 nm being visible in when E is directed across the long axis of the rod, and a longitudinal resonance at 700 nm becomes visible when E is directed parallel to the long axis.…”

Here we explore the unusual plasmon resonances of crossed gold nanorod structures of varying geometries. Using numerical simulations, we show that the resonances of simple rods are hybridized and blue-shifted in the composite structures and that these structures are surrounded by spatially extended and high intensity electric fields. This attribute suggests several potential uses for these shapes, for example as a nano-antenna for the generation of two-photon fluorescence.

Over the past decades, a new branch of plasma research, the nanomaterial (NM) synthesis by plasma-liquid interactions (PLIs), is rapidly rising, mainly due to the recently developed various plasma sources operated from low to atmospheric pressures. The PLIs provide novel plasma-liquid interfaces where many physical and chemical processes take place. By exploiting these physical and chemical processes, various NMs ranging from noble metal nanoparticles to graphene nanosheets can be easily synthesized. The currently rapid development and increasingly wide utilization of the PLI method naturally lead to an urgent requirement for presenting a general review. This paper reviews the current status of research on plasma-liquid 2 interactions for nanomaterial syntheses. Focus is on the comprehensive understanding of the synthesis process and perceptive opinions on the present issues and future challenges in this subject.

“…Since then, a plethora of studies have dealt with the production and characterization of noble metal colloids in a wide range of sizes [2][3][4], and for a variety of applications, including catalysis [5], biolabelling [6], biosensing [7], optical switches [8], among others. Only recently, variations in nanoparticle shape have been recognized as having a strong impact on their properties, which has motivated the development of synthetical methods for the preparation of particles with various geometries, such as rods [9][10][11][12][13], wires [14][15][16], prisms [17][18][19][20][21], cubes [22][23][24] and other polyhedrons [25,26].…”

Dynamic Light Scattering of Short Au Rods with Low Aspect Ratios

et al. 2007

The translational and rotational diffusion of a series of gold nanorods with low aspect ratio was investigated by dynamic light scattering (DLS). It is shown that the translational and the rotational diffusion coefficient can be determined because the particle shape causes an anisotropy of the polarizability. This gives rise to two clearly distinguishable relaxation modes in the time correlation function of the scattered light. The particle length and aspect ratio were determined independently by transmission electron microscopy (TEM). Using a hydrodynamic model, these geometrical parameters were converted to diffusion constants, which agree well with the values determined by DLS. Additionally it is possible to obtain an estimate of the particles aspect ratio from the amplitude ratio of the two relaxation modes.
