Colloidal silver nanospheres, nanorings, and nanonetworks were synthesized by the nanosecond pulsed laser ablation of a silver metal plate in a pure distilled water (at room temperature) using the fundamental (1064 nm), second harmonic (532 nm), and third harmonic (355 nm) wavelengths of the Nd:YAG laser, respectively. The products were characterized by means of both transmission electron microscopy (TEM) and optical absorption spectroscopy. The TEM data show the formation of silver nanospheres, nanorings, and nanonetworks. On the other hand, optical spectra reveal the occurrence of the red shift of the peak associated with the surface plasmon resonance (SPR) of silver nanorings and nanonetworks. A possible explanation for the formation of above stated silver nanostructures is being discussed
