Acoustic vibrations of Au and Ag elongated nano-objects with original morphologies, from Ag–Ag homodimers to Au@Ag–Ag heterodimers and Au@Ag eccentric core–shell spheroids, have been experimentally investigated by ultrafast time-resolved optical spectroscopy. Their frequencies, obtained by the analy...
