12. Appendix 2. Analytical model to describe plasmon resonance

Metallic nanoparticles are increasingly used in both fundamental research and industrial applications. However, given the nanometric size of these objects, it is often difficult to obtain an immediate diagnosis of NP size and quantity using microscopy methods. In many cases, optical absorption spectroscopy can provide useful information. The analytical model proposed here is very simple to implement and enables an initial quantitative analysis of absorption spectra of metallic NP suspensions.

12.1 Simple electromagnetic modeling

Electromagnetism and the solution of Maxwell's equations in a medium characterized by its dielectric permittivity ε (a possibly complex function of the pulsation ω of the exciting wave) enable us to calculate the propagation of light...
