Abstract
Acoustic damping of lithographed gold nanodisk vibrations was investigated using single-particle timeresolved spectroscopy. A strong influence of morphology (diameter/height ratio) on their vibrational quality factors was experimentally demonstrated and confirmed by numerical modeling. These findings thus open new possibilities for engineering the vibrational modes of nanoobjects.
