A simple method is described for preparing silver nanoparticles via photoreduction in layered laponite suspensions without any additional reduction agent or heat treatment. The properties of silver nanoparticles were studied as a function of the UV irradiation time. Transmission electron microscopy (TEM) was employed to study the variation of particle shape, size and size distribution. The crystal structure of silver nanoparticles was characterized powder X-ray diffractometry (XRD). The optical absorption spectra of silver nanoparticles were obtained by ultraviolet-visible (UV-Vis) spectroscopy.
