Figure 4

The optical characteristics of the silver solution. (a) The extinction spectra of the silver nanostructure solution obtained with different PVPs of 0.286 M. (b) The extinction spectra of the silver nanostructure solution obtained at different concentrations of PVPMW=29,000, (c) The extinction spectra of the silver nanostructure solution obtained at different concentrations of PVPMW=40,000. (d) The extinction spectra of the silver nanostructure solution obtained at different concentrations of PVPMW=1,300,000.
