Preparation and Characterization of Silver Nanospheroids: Theoretical and Experimental Approaches

Mounira Amraoui, Chouaib Daoudi, Mohamed Remram


We synthesized silver nanoparticles of different sizes and forms as function of the molar masses of AgNO3, in two different solvent mediums (ethanol, methanol). We carried out the synthesis according to standard chemical route with major modifications. The spectroscopic characterization showed the presence of two distinct absorption bands; the first band at 300 nm and the second shifted to 440 nm. We found a multipolar phenomenon depending on the temperature. The shape and size predicted by the numerical model are conform to the experimental results. The study demonstrated that the nanoparticles have a spheroidal shape.
