It is known that silver (Ag) nanoparticles are attractive due to their novel and mild chemical and physical properties. In this research, anisotropic mono-dispersed silver nanoparticles are synthesized via a simple chemical reduction method and assisted by Daxad 19 surfactant. The reactant temperatures and weight ratios of the chemical constituents play a key role in controlling the hybrid shaping mechanism. The results indicate that the reduction rate of Ag+ to Ag-0 nanoparticles is enhanced significantly with increasing weight ratios of Daxad 19 and AgNO3 under controlled reactant temperature. The results show that the as-prepared silver nanoparticles are well-dispersed and uniform in size and shape. The dimensions of the particles are easily controlled. A comparison between experimental absorbance UV-visible spectra and simulated spectra from Mie's Scattering Theory is carried out. It is observed that the simulated spectrum confirms well with the optical behaviour of the experimental spectra. (C) 2011 Elsevier B. V. All rights reserved.
