Preparation of silver and gold nanoparticles by novel pin-hole DC plasma source
Original language description
Silver and gold nanoparticles were produced using the pin-hole discharge generated by dc non-pulsing high voltage directly in precursor solution. Silver nitrate solution was used as the precursor for silver nanoparticles, chloroauric acid was used as the precursor for gold nanoparticles. Effects of discharge time, precursor concentration and additives such as reduction agent (ethylene glycol) and capping agent (polyethylene glycol and sucrose) were studied. Nanoparticles were mainly analysed by UV-VIS spectrometry. The size of prepared nanoparticles was determined by dynamic light scattering with backscattering detection. To determine the stability of NPs, Zeta potential was measured by electrophoretic light scattering. Formation of silver and gold nanoparticles was than confirmed by SEM/EDS analysis. Both kinds of particles had spherical shapes.
