论文摘要
在这项实验中,作者回顾了金丝纳米晶体的合成和表征的原理和方法,并提出了两种可能的金和银复合纳米晶体的合成机制。通过“柠檬酸钠无籽方法”制备金纳米晶,银纳米晶体以及金和银复合纳米晶体(Turkevich方法)。产物的特征是动态光散射(DLS),紫外线光谱(UV)和扫描电子显微镜(SEM)。通过比较实验,分析了金丝纳米晶体不同合成序列背后的合成机制。讨论了观察到的外来现象。
In this experiment, the authors reviewed the principles and methods for the synthesis and characterization of gold-silver nanocrystals and proposed two possible synthesis mechanisms for Gold and Silver Composite Nanocrystals. Gold nanocrystals, silver nanocrystals, and Gold and Silver Composite Nanocrystals were prepared by the "Sodium citrate seedless method"(Turkevich Method). The products were characterized by dynamic light scattering (DLS), ultraviolet-visible light spectroscopy (UV), and scanning electron microscopy (SEM). Through comparative experiments, synthesis mechanisms behind different synthesis sequences of gold-silver nanocrystals are analyzed. Observed exotic phenomena are discussed.
