Fig. 8. .(A) TEM image of uniformly dispersed spherical-like gold nanoparticles (AuNPs). (B) Size distribution of AuNPs measured by TEM image analysis (n = 330; dashed line represents the normal distribution of the data). (C and D) HRTEM images of a single AuNP (zoomed), with typical AuNP diameter (arrow), and the nanocrystallinity by the well-defined interplanar distance. (E) SAED ring patterns of AuNPs. (F) Typical EDS spectrum of AuNPs.
