Abstract

A closer look: The growth mechanism of nanoparticles is difficult to elucidate by common UV/Vis and TEM methods, owing to ensemble averaging and 2D projection effects. Single-particle scattering spectra were now used to investigate the overgrowth of gold on gold/polystyrene nanoparticles. Three patterns are readily differentiated, and corresponding overgrowth mechanisms are proposed.
