Au–Ge and Ag–Ge Heterodimers with Tunable Domain Sizes: A Supersaturation-Precipitation Route to Colloidal Hybrid Nanoparticles

摘要: Colloidal hybrid nanoparticles, which contain multiple inorganic domains that are joined together through solid–solid interfaces, exhibit particle multifunctionality as well new and enhanced properties can emerge from the particle–particle interactions. These nanoparticles typically synthesized using heterogeneous seeded nucleation of one nanoparticle on surface another phase segregation, dewetting core–shell fusion premade nanoparticles. However, to expand materials diversity potential range applications such systems, alternative routes needed. Here, we show solution–liquid–solid related supersaturation-precipitation strategies, traditionally used in synthesis 1D structures nanowires nanorods, also be applied colloidal Specifically, Au Ag serve seeds...
