Tunable Localized Surface Plasmon Resonance of Gold Nanorod by Control of Sodium Oleate
Main Article Content
Abstract
Gold nanorods (AuNRs) are powerful plasmonic nanomaterials with tunable localized surface plasmon resonance (LSPR) that make them ideal for surface-enhanced Raman scattering (SERS) sensing. In this work, we report results on a sodium oleate (NaOL)-assisted seed-mediated synthesis of AuNRs in a cetyltrimethylammonium bromide (CTAB)-based system. Varying NaOL amount allowed to control the nanorods aspect ratio, improve monodispersity. The resulting products have been checked on X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and energy-dispersive X-ray spectroscopy (EDS).
Keywords: Gold nanorods, localized surface plasmon resonance, sodium oleate, surfactant.
