Abstract:
We have grown silver prisms and pentagonal bipyramids, induced by plasmon excitation on a colloidal solution under the irradiation of light emitting diodes of different colors. Two methods of synthesis of the seeds were tested and their growth evolution recorded, in order to analyze the effect of the chemical synthesis and the color of the irradiation on the morphology and size of the final product. We show that the conversion rate into anisotropic nanoparticles is determined by the chemical environment and the shift of the irradiation wavelength with respect to the plasmon resonance of the seeds. The conversion rate defines the final morphology of the nanoparticles, whereas the size of the nanoparticles is univocally determined by the wavelength of irradiation, irrespective of the method to prepare the seed solution. © 2013 Elsevier B.V.

- The initial increase of the plasmon resonance extinction peak at 400 nm in Fig. 2(b) is attributed to the formation of spherical silver NPs from Ag + ions that did not react previously. This hypothesis is reinforced by the shift of the maximum extinction peak to the blue. It is known that Ag+ ions in colloidal silver NPs may be absorbed at the surface of the NPs, to result in a change in their electronic density. This fact shifts the plasmon absorption band to blue when Ag+ concentration decrease. Thus, the plasmon shift is indicating the decrease in Ag+ concentration that is reduced to form metallic NPs. After 56 h of reaction a decrease of the extinction peak of s-NPs is observed, indicating that the s-NPs concentration decreases; Parakhonskiy, B.V., Bedard, M.F., Bukreeva, T.V., Sukhorukov, G.B., Möhwald, H., Skirtach, A.G., (2010) J.
