Abstract

A study is performed of the effect the content of sodium citrate in a reaction mixture (an aqueous solution of silver nitrate and sodium citrate) has on the photochemical production of anisotropic silver nanostructures with a required optical spectrum of localized surface plasmon resonance. Silver nanostructures form during the photochemical reduction of silver nitrate (1 × 10^–4 M) at different concentrations (5 × 10⁻⁴ M− 1 × 10⁻¹ M) sodium citrate. The optimum conditions for the formation of silver nanoparticles (NPs) with decahedral geometry, dendritic NPs (fractal aggregates), and spherical silver NPs are determined.

柠檬酸钠对具有所需局域表面等离子体共振光谱的银纳米结构光化学生产的影响

摘要

对反应混合物（硝酸银和柠檬酸钠的水溶液）中柠檬酸钠的含量对具有所需局部表面等离子体共振光谱的各向异性银纳米结构的光化学生产的影响进行了研究。银纳米结构在硝酸银（1 × 10 ^–4 M）在不同浓度（5 × 10 ^-4 M− 1 × 10 ^-1 M）柠檬酸钠的光化学还原过程中形成。确定了形成具有十面体几何形状的银纳米粒子 (NPs)、树枝状纳米粒子 (分形聚集体) 和球形银纳米粒子的最佳条件。
