What Factors Influence the Extinction Cross Section?
Several factors impact the extinction cross section of nanoparticles:
Size of nanoparticles: Larger particles typically have higher scattering cross sections. Shape of nanoparticles: The geometry of the particle can influence both scattering and absorption. Material composition: Different materials will have different intrinsic absorption and scattering properties. Wavelength of incident light: The extinction cross section is wavelength-dependent, especially near resonance conditions.
