Gold nanoparticlesInterparticle fusionsLongitudinal surface plasmon resonanceSeed – growth (S – G) method was used to synthesize gold (Au) nanoparticles (NPs) in the presence of water soluble star polymers "tetronics" to investigate a unique photophysical behavior of Au NPs. They produced absorbance...
aBased on the above study results, the two absorption peaks appeared in Fig.1(A) should result from the transversal and longitudinal surface plasmon resonance of electrons in silver nanorods 凭上述研究结果,二吸收峰出现在(A) 在银色nanorods应该起因于电子横截和纵向表面胞质基因共鸣[translate]...
An analytical expression for the surface plasmon resonance sensitivity with respect to changes in the refractive index of surrounding media is obtained.doi:10.1016/j.cplett.2007.12.032A. MelikyanH. MinassianElsevier B.V.Chemical Physics Letters...
In addition, the synthesis of high purity nanorods with longitudinal surface plasmon resonance (LSPR) peak higher than 1000 nm is particularly difficult utilizing this technique. This report demonstrates the use of hydroquinone for the synthesis of gold nanorods which addresses these two major ...
For both cases, the absorption spectra are calculated for various incidence angles and interparticle distances to reveal the optical anisotropy related to the geometry of the system through the splitting of the surface-plasmon resonance (SPR) into the transverse and longitudinal modes. This effect ...
surface plasmon resonanceultrafast optical responseWe utilized a co-sputtering technique without any templates, featuring growing and etching synchronously, to delicately fabricate dense and ultrafine Ag nanowire arrays/alumina matrix composite films. Both the diameter and separation distance of the Ag ...
Topographical changes to the array surface caused by protein immobilization were demonstrated by applying atomic force microscopy and ellipsometry. The resonance wavelengths of SPR spectra were red shifted according to the increase in thickness of the dielectric layer by protein immobilization. 展开 ...
(b) 500 nm and height 950 nm recorded as a function of the lattice period. The horizontal dashed line indicates the weak phonon resonance. The lower panel shows the magnitude of the reflectance dip extracted from the data. The shaded region indicates the region where the upper polariton ...
Nanorods were the selected nanostructures, as their longitudinal plasmon resonance has the potential to cover the NIR spectral limitation. The study aims to ... Carvalho, Diogo F.,Teixeira, Jennifer P.,Salome, Pedro M. P.,... - Solar Energy Materials and Solar Cells: An International Journal...
The effect of geometrical as well as material parameters on the longitudinal localized plasmon resonance of the trimer nanosystem was investigated. The results provide insight in to the possible tunability of the localized plasmon modes which could find application in designing of chemical and ...
