Preparation of Ag Nanoparticles by Particulate Radiation of Pulsed Electron Beam

Abstract:

Nano metal Ag nanoparticles were synthesized by pulse electron beam (e-beam) irradiation at room temperature and the atmospheric pressure. The staring materials were AgNO₃, toluene, ethanol and ethylene glycol. The ethanol and ethylene glycol plays a role of prohibiting agglomeration of metal ions. Energy dispersive X-ray spectrometer (EDX) was used to characterize the elements. Transmission electron microscopy (TEM) images were used to determine the shape and diameter. The time of e-beam irradiation affect to the particle size and aggregation. The average particle size was 10 nm and 30 nm for the dose time of 1 and 5 min, respectively. The shape of particles were changed from spherical to disk-like to coral-like, with increasing the irradiation time from 1 to 5 to 10 min.
