Implication

Microscopy and numerical modeling reveal large local optical activity in fractal silver nanoparticle clusters, indicating broad and random spatial distributions of chiral plasmon modes.

Key Points

  • To investigate the origin and spatial distribution of large local optical activity in random fractal aggregates of silver nanoparticles.
  • Observed local optical activity in silver nanoparticle fractal aggregates using photon scanning tunneling microscopy.
  • Performed numerical simulations analyzing dipole-moment distributions under right- and left-circularly polarized incident illumination across varied cluster dimensions.
  • Demonstrated significant differences in local dipole-moment distributions between right- and left-circularly polarized light when cluster dimensions equaled or exceeded the incident wavelength.
  • Observed wide variations in the local circular intensity difference of scattered light, confirming the presence of broadly and randomly distributed chiral plasmon modes.
