Abstract:

Monodispersed silver nanoparticles were prepared via chemical reduction method at room temperature using silver halide or silver oxide as precursors and water as solvent. Controllable particle sizes were achieved by changing the precursors. Scanning electron microscope (SEM), UV-Vis Spectroscopy (UV-Vis), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS) were used to characterize the morphology and the composition of the silver nanoparticles. The results showed that the as-prepared silver nanoparticles have high monodispersity with a particle size of 40150 nm, and have face-centered cubic polycrystal structure. The silver nanoparticles would have promising applications in the field of printed electronics, etc.

Key words: silver nanoparticles, silver halide, silver oxide, monodispersity, particle preparation
