Fig. 3. (a) Dark-field images of 19 particles in a visual field during the electrochemical deposition of CdS on AuNPs. (b) The R/G value variation of each particle with time elapsed (scale bar: 1 μm). (c) The estimated average shell thickness dependence upon the ΔR/G value; the data were fit to a line with the equation y = 2.35 – 2.35 exp(–0.06x).
