Gold Nanoparticles with Elongated Shapes: Synthesis and Optical Properties

Year: 2012

Type: article

Abstract: We use a seed-mediated growth to fabricate gold nanorods in water solution.By changing the amount of silver salt we demonstrate the control of aspect ratio of the obtained rods.The microscopic and spectroscopic analyses provide ways to characterize the morphology and the optical properties of the gold nanorods.Nanorods synthesized using this approach feature length of the order of 5060 nm, which translates into longitudinal plasmon resonances in the near infrared spectrum region.
