  • Particle size is not the sole determinant of luminescence; surface ligands play a crucial role.
  • Valence states of metal atoms and the crystallinity of nanoparticles significantly affect emission properties.
  • Diverse structural factors collectively influence the photoluminescence mechanisms.

Conclusions:

  • A comprehensive understanding of structural factors beyond size is essential for controlling and optimizing nanoparticle luminescence.
  • Tailoring surface chemistry, valence states, and crystallinity offers pathways to engineer specific photoluminescent behaviors in gold nanoparticles.
