Based on our previous work of MSA influence on silver nano particles formation we have performed a series of research related to the preparation and characterization of silver nanoparticles which synthesized through coprecipitation process. The silver nano particles was transformed into silver nanoparticles films by spin coating deposition method. The silver nanoparticles were prepared from silver acetate as precursor, reductant agent phenylhydrazine, and dodecylamine as stabilizer. X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Analysis (EDAX), and Electric Four Point Probe have been used to characterize the silver nanoparticles as well as the films. The morphology and the crystal structure have been determined by means of XRD and SEM. The average grain size of silver nanoparticles is found to be 22 nm. The peaks in XRD pattern are in good agreement with that of face-centered-cubic phase of metallic silver. The electrical conductivity films were confirmed in the range of conducting material. The highest conductivity was reached at 3,88 x 109 S/cm associated to 1600 rpm of spin coater rotation. © (2014) Trans Tech Publications, Switzerland.
