Synthesis of gold nanorods using a mixed reducing agent hydroquinone–ascorbic acid
A new mixed reduction system for the synthesis of gold nanorods (NRs), including ascorbic acid and hydro- quinone, has been proposed. Dependence of NRs longitudinal plasmon resonance band position on the concentration of silver ions, ascorbic acid and hydroquinone during synthesis were found, which makes it possible to obtain NRs with required op- tical properties. It was found that when using a mixed reducing agent, higher monodispersity and morphological yield can be achieved as compared to individual reducing agents, which is especially important for obtaining short NRs with a maximum of longitudinal plasmon resonance in the region of 600–700 nm.
