Synthesis of well-defined silver nanostructure in terms of size and shape has been strongly motivated by the requirements to their size-and shape-dependent optical properties which achieve their practical applications ranging from biosensing to catalysis and optics. In this Letter, an ultrafast synthetic process for the well-defined Ag nanocubes and nanowires have been developed, which simply involve the microwave-mediated polyol reduction of silver nitrate in ethylene glycol by adding different amount sodium sulfide (Na2S) into the solution. The possible growth and evolution process of the Ag nanocubes and nanowires involves the microwave ultrafast nucleation and growth followed by oxidative etching of Ag nanocrystals.
