Preparation of high quality Ag film from Ag nanoparticles

A simple route to the high quality Ag film was developed at room temperature by using Ag nanoparticles stabilized by polyvinylpyrrolidone (PVP) as Ag source. The scanning electron microscopy (SEM) images indicate that the silver film prepared on the quartz substrate is smooth and dense. Meanwhile, the X-ray diffraction (XRD) of the film shows a face-centered cubic (fcc) phase of Ag.
