Abstract
Side-by-side connected gold nanorod dimers were formed by ligand substitution of hexadecyltrimethylammonium bromide (C16TAB) bilayer with 1-hexylamine. The addition of 1-hexylamine caused a gradual aggregation of gold nanorods, which was verified from blue shift of the longitudinal localized surface plasmon resonance (LSPR) band of gold nanorods. Dimers were found to be preponderant at about 4 h from the addition of 1-hexylamine. Raman intensity of Rhodamine 6G (R6G) molecules in the presence of gold nanorod dimers exhibited a 50-fold and a 15-fold enhancement compared with that of aqueous R6G solution without gold nanorods and with gold nanorod monomers, respectively.
