摘要

提出了一种以抗坏血酸和氢醌为主要原料合成金纳米棒的混合还原体系。研究发现，合成过程中银离子、抗坏血酸和对苯二酚的浓度与核磁共振的纵向等离子体共振带位置有一定的关系，这使得制备出具有理想光学性能的核磁共振成为可能。研究发现，与单一还原剂相比，使用混合还原剂可以获得更高的单分散性和形态产率，这对于获得最大纵向等离子体共振在600-700 nm区域的短核磁共振尤为重要。

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.
