摘要：

With 50nm gold nanoparticles as seeds, a series of spherical monodispersed gold nanoparticles(size from 60nm to 160nm) were obtained by surface autocatalytic reaction. The gold sols were characterized using transmission electron microscopy(TEM) and UV-Vis spectrometry, The size of nanoparticles can be conveniently predicted by controlling the molar ratios of the total gold species in solution to that in seeding sols, The morphology of resulted gold nanoparticles was found depending on the reagent-adding sequences.
