Stabilization of sputtered gold and silver nanoparticles in PEG colloid solutions

Popis výsledku v původním jazyce

In this study, a simple technique for preparation of colloid solution of metal nanoparticles in polyethylene glycol (PEG)/H2O is described. By this technique, stable colloidalmetal solutions can be prepared ready for use without application of chemical reactions, stabilizers, or reducing agents. The nanoparticles are created by direct sputtering of metal into PEG. The influence of sputter conditions and the concentration of PEG/H2O on the properties of nanoparticles was studied. The nanoparticles were characterized by transmission electron microscopy, atomic absorption spectrometry, dynamic light scattering, and UV-Vis spectroscopy. UV-Vis spectra of gold nanoparticle solution exhibit localized surface plasmon resonance characteristic peaks located inthe region 513-560 nm (PEG/H2O-1/1), 509-535 nm (PEG/H2O-1/9), and for silver nanoparticles in the region from 401 to 421 nm. Silver nanoparticles have a broader size distribution compared with gold ones. An appropriate choice of concentr
