摘要：

Silver nanoparticles have been prepared under microwave irradiation from a solution of silver nitrate. Different morphologies of silver colloids with charming colors could be obtained using two different reducing agents namely sodium citrate (SC) and N1, N2-diphenylbenzamidine (DPBA) or simply amidine. The structures of silver colloids were determined by TEM. UV-Vis spectroscopy was used to follow the reaction process and to characterize the optical properties of the resultant silver colloids. The influence of two different mild conventional and unconventional reducing agents on the morphology of silver was investigated.
