Lusters are composite thin layers of coinage metal nanoparticles in glass displaying peculiar optical
properties and obtained by a process involving ionic exchange, diffusion, and crystallization. In
particular, the origin of the high reflectance (golden-shine) shown by those layers has been subject of
some discussion. It has been attributed to either the presence of larger particles, thinner multiple
layers or higher volume fraction of nanoparticles. The object of this paper is to clarify this for which
a set of laboratory designed lusters are analysed by Rutherford backscattering spectroscopy,
transmission electron microscopy, x-ray diffraction, and ultraviolet-visible spectroscopy. Model
calculations and numerical simulations using the finite difference time domain method were also
performed to evaluate the optical properties. Finally, the correlation between synthesis conditions,
nanostructure, and optical properties is obtained for these materials. |
