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. <br /> <br /> Full Text: <a class="file" href="/PLP/index.php/letters/article/view/9-23/488" target="_parent">PDF</a> <br /> <br /> <strong>References</strong><ol><li>Cecilia Noguez, "Surface Plasmons on Metal Nanoparticles: The Influence of Shape and Physical Environment", J.
