With 50nm ld nanoparticles as seeds, a series of spherical monodispersed ld nanoparticles(size from 60nm to 160nm) were obtained by surface autocatalytic reaction. The ld 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 ld species in solution to that in seeding sols. The morphology of resulted ld nanoparticles was found depending on the reagent-adding sequences.
