Figure 12

a, b TEM images of gelatin-Ag–AuNPs with different ratios of silver to gold synthesized at 80°C. a nAg/nAu = 2.4, V AgNO 3 : 2 mL, V HAuCl 4 : 1 mL; b nAg/nAg = 1.2, V AgNO 3 : 2 mL, V HAuCl 4 : 2 mL, the inset in b is magnification of the image marked by pane in b; c UV–vis spectra of Ag–AuNPs, AgNPs and AuNPs. (1) AgNPs (Cgelatin: 0.4 wt%, V AgNO 3 : 2 mL), (2) Ag–AuNPs in Figure 12a, (3) Ag–AuNPs in Figure 12b, (4) AuNPs (Cgelatin: 0.4 wt%, V HAuCl 4 : 2 mL); d XRD of gelatin-Ag–AuNPs film dried at room temperature under vacuum. Peaks marked with stars arise from gelatin organic phase.
