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.
