AFM images revealing the 2D/3D morphology of the SNPs for samples (a)/(d) HM_Y10S, (b)/(e) HM_Y20S and (c)/(f) HM_Y30S. 2D/3D AFM images of the GNPs for samples (g)/(j) HM_Y10G, (h)/(k) HM_Y20G and (i)/(l) HM_Y30G. The insets in (a,g) are the dark-field images of the corresponding samples, both obtained from 10 nm thick deposited films.
