Effect of reducing agents on the synthesis of anisotropic gold nanoparticles.

ABSTRACT: The seed-mediated method is a general procedure for the synthesis of gold nanorods (Au NRs), and reducing agents such as ascorbic acid (AA) and hydroquinone (HQ) are widely used for the growth process. Further, they are mild reducing agents; however, when AA is used, controlling the size of Au NRs with a higher aspect ratio (localized surface plasmon resonance (LSPR) peak, λ_Lmax > 900 nm) is challenging because it results in a faster growth rate of Au NRs. In contrast, when HQ is used, Au NRs with a higher aspect ratio can be synthesized as it slows down the growth rate of the Au NRs and greatly enhanced the λ_Lmax. However, the increase in λ_Lmax is still needs not satisfactory due to the limited enhancement in the aspect ratio of Au NRs due to utilization o
