dc.description.abstract | were deposited on flat substrates by physical vapor deposition in a glancing angle
configuration. The particles were characterized by scanning electron microscopy and atomic
force microscopy and their optical properties examined by UV–vis absorption spectroscopy
using linearly polarized light. It was found that, depending on the amount of deposited silver
and the evaporation angle, part of the ‘as-prepared’ samples present NPs characterized by an
anisotropic shape and a polarization dependent SPR absorption and different colors when
using polarized white light at 0 and 90 . Low-power irradiation of these materials with an
infrared Nd-YAG nanosecond laser in ambient conditions produced an enhancement in such
dichroism. At higher powers, the dichroism was lost and the SPR bands shifted to lower
wavelengths as a result of the reshaping of the silver NPs in the form of spheres. The possible
factors contributing to the observed changes in dichroism are discussed. | es |
