Fig. 3. UV-vis absorption spectra of silver colloids prepared in aqueous binary polyol solutions by varying the concentrations of (a) EG and (b) PEG 0.4. The absorption intensities were obtained with a three-fold dilution. (c) Viscosity of an aqueous binary polyol solution with varying the concentrations of EG and PEG 0.4. (d) Mole ratio of hydroxyl group to ether oxygen in a binary polyol solution as a function of the concentrations of EG and PEG 0.4.
