Abstract
A method for the reduction of AgNO3 in aqueous Daxad 19 solution is presented in this study. The relationships between the size, shape and optical properties of silver nanoparticles are highlighted while controlling synthesis. The variation of size and shape of silver nanoparticles with the change in reactant temperatures are obtained from the transmission electron microscopy images. Ultra violet-visible spectra show that the Surface Plasmon Resonance peak is shifted to the lower wavelength with decreases in particle size. Gibbs free energies (Gf) of silver nanoparticles were calculated by using the data obtained from UV-Vis spectra. Calculation results proved that the Gf of silver nanoparticles have an intimate relationship with the particle size and shape. Gf increases significantly with decrease in particle size. However, the value dropped significantly after the increase in particle size.
