摘 要：With a two-phase method,well-dispersed 5.2 nm Ag nanoparticles with narrow size distribution （±0.5 nm） are synthesized.The assembled structures of colloidal Ag nanoparticles on highly oriented pyrolytic graphite （HOPG）,silicon chip and microscopic glass have been investigated by atomic force microscopy （AFM）.With different spin-coating speeds and concentrations of colloidal silver nanoparticles,various assembly structures could form on those substrates.On HOPG,Ag nanoparticles were absorbed and aligned along single-atom-height step edges to form a linear one-layer structure.And on silicon chip and microscopic glass,one-layer closed packing fractal structure and two-layer closed packing ring were observed respectively.
