Electrochemical Method for Ag-PEG Nanoparticles Synthesis
Figure 7
UV-Vis spectra of Ag nanoparticles obtained by using different polymer concentrations of PEG-2000 during the synthesis process. From the bottom to the top: 0.5, 1.0, 1.5, and 2.0% w/v. In the figure, the plasmon position is indicated for each spectrum.
