Abstract

We determine the surface plasmon resonance (SPR) band values of nanorods gold nanoparticles as function of silver nitrate and seeds solution volume.Seed-mediated growth process is used to prepare gold nanorods. The influence of silver nitrate and seeds solution volume was studied using the characterizations techniques: UV-Vis-NIR and TEM. The results showed the nanoparticles obtained increasing silver nitrate and seeds solution volume were proved to produce a maximal longitudinal SPR (SPRL) response and good dispersion. Homogeneous nanorods were obtained under conditions with optimized seed volume.The SPR performance of the nanoparticles was systematically evaluated using volume silver nitrate (80 l to 160l) and volume seeds (15 l to 45l).The resonance frequency show an evolution toward high wavelength, results for these structures demonstrated potential applications in windows optical.
