Abstract:Bimetallic Au/Ag core–shell cuboid nanoparticles (NPs) exhibit a complex plasmonic response dominated by a dipolar longitudinal mode and higher-order transverse modes in the near-UV, which may be exploited for a range of applications. In this paper, we take advantage of the strong signature of these modes in the NP ultrafast transient optical response, measured by pump-probe transient absorption (TA) spectroscopy, to explore the NP vibrational landscape. The fast Fourier transform analysis of the TA dynamics r… Show more
“…Otomalo et al [7] reported the preparation of Au/Ag core-shell bimetallic nanocuboids NPs. These show complex plasmonic phenomena, with dipolar longitudinal modes and higher order transverse modes.…”
In the last decade, new technologies have undertaken an extraordinary development, based not only on new materials and new processes but also on design, modelling, information technology, and artificial intelligence [...]
