چکیده
|
The spectra of small gold nanoparticles (gnps) were theoretically described following the modified mie equations and by adopting the kriebig-drude model. the experimental dependence of the absorption maximal intensity of small spherical gnps versus their diameter was compared with a theoretically derived relation. the theoretical description is validated by simultaneously obtained data from uv-vis plasmon absorption spectra together with the size of gnps measured by means of atomic force microscopy (afm).
