Abstract (AI)
This tutorial review presents an overview of theoretical methods for predicting and understanding the optical response of gold nanoparticles. A critical comparison is provided, assisting the reader in making a rational choice for each particular problem, while analytical models provide insights into the effects of retardation in large particles and non-locality in small particles. Far- and near-field spectra are discussed, and the relevance of the latter in surface-enhanced Raman spectroscopy and electron energy-loss spectroscopy is emphasized.
Key Findings
1
Analytical models also reveal the effects of non-locality in smaller gold nanoparticles.
2
Analytical models clarify how electromagnetic retardation influences the optical response of larger gold nanoparticles.
3
Both far-field and near-field optical spectra are addressed, with near fields highlighted as important for surface-enhanced Raman spectroscopy and electron energy-loss spectroscopy.
4
The comparison is intended to support rational selection of modeling approaches for specific gold-nanoparticle optical problems.
5
The tutorial review critically compares theoretical methods for predicting and interpreting the optical response of gold nanoparticles.
