Gold Nanorods:  Electrochemical Synthesis and Optical Properties

Abstract: Aqueous solutions containing a high yield of suspended gold nanorods have been successfully synthesized via an electrochemical method. The control of preparing gold nanorods with different aspect ratios can be attained. Their absorption spectral features show a dominant surface plasma band corresponding to the longitudinal resonance, SPl, and its λmax shifts markedly to the red as the aspect ratio is increased. Meanwhile, the dependence of λmax for longitudinal resonance on the mean aspect ratio shows a deviat… Show more

“…A wide variety of anisotropic particles with diverse anisotropy in size, shape [1][2][3][4][5][6][7] and chemical functionality [8][9][10][11][12][13][14][15][16][17][18][19][20] has been explored. Within such a large diversity of anisotropic particles, significant attention has been given lately to the study of surface-anisotropic particles, that is, particles exhibiting multiple surface functionalities, while often having an isotropic polymer core.…”

“…This is especially true for noble metal nanoparticles, where the plasmonic and catalytic properties can be finely tuned through control over their morphology. [1][2][3][4][5][6][7] Indeed, a variety of metallic nanostructures with well-defined shapes have been synthesized via photochemical, 1,[8][9][10][11] thermal, 12-14 electrochemical, 15 and template-directed methods. 2,16 These synthetic strategies provide a means to chemically control the morphology of particles and, consequently, their catalytic, optical, electrical, and magnetic properties.…”

“…However, according to the authors [7,8], the C 16 TAB and TC 12 AB in solution form cylindrical-shape C 16 TAB-TC 12 AB micellar frameworks, which may assist nanorod formation as more and more gold ions are introduced into these micelle structures. At the appropriate temperature, the addition of acetone makes loosening the micellar framework, facilitating the introduction of the gold ions into the micellar frameworks, in this way the gold nanorods are easily developed.…”

“…Second, most metals crystallize in highly symmetric cubic lattices. Therefore, soft and rigid templates had been used to achieve rod-shaped metal nanostructures, so the seeded method [2,3] and sonoelectrochemical [6,7] is often used.…”
