Figure 2

(a,b) STEM images in which both Au NPs and Au NSs are observed in the LDH substrate. Scale bar, 100 nm for a and 50 nm for b. The selected regions are enlarged as the insets, and line scanning was performed over the NSs following the two arrows. (c,d) The normalized STEM intensity (green histogram) and the Au M-edge EDX intensity (red curves) line profiles, collected along the red arrows in a,b, respectively. (e,f) The STEM intensity line profiles collected along the blue arrows in (a,b), respectively. The EDX results confirm that the NSs are made of Au; the thickness of the Au NSs can be determined based on the STEM intensity by using Au NPs as a reference.
