Kp. Charle et al., THE SURFACE-PLASMON RESONANCE OF FREE AND EMBEDDED AG-CLUSTERS IN THESIZE RANGE 1,5 NM-LESS-THAN-D-LESS-THAN-30 NM, Crystal research and technology (1981), 33(7-8), 1998, pp. 1085-1096
It is experimentally proven that the size dependence of the surface pl
asmon resonance of large spherical silver clusters is related to the s
urface optical properties of Ag. It is also demonstrated that there is
a minimum size, below which this approach fails as expected, and that
there is a maximum size, above which the surface contribution can be
neglected such that classical optics applies.
