Fig. 4. HRTEM, XRD and UV/Vis investigations of the synthesis of silver nanoparticles at 90 °C. (a) Micrographs for larger (left) and smaller (right) silver nanoparticles, showing an interplanar distance of 2.34 Å. (b) FFT analysis results indicating the (111) planes. (c) XRD data with Rietveld refinement of silver nanoparticles obtained after 70 min. Peaks and Miller indices of silver and byproduct AgCl are indicated. (d) UV/Vis spectra of silver nanoparticles taken after 24, 36, 54 and 72 min during SAXS experiments.
