Gold nanorod plasmonic upconversion microlaser [PDF]

14th IEEE International Conference on Nanotechnology, 2013
Plasmonic-photonic interactions have stimulated significant interdisciplinary interest, leading to rapid innovations in solar design and biosensors. However, the development of an optically pumped plasmonic laser has failed to keep pace due to the difficulty of integrating a plasmonic gain material with a suitable pump source.

Enhanced Sputtering Yields from Single-Ion Impacts on Gold Nanorods [PDF]

, 2013
Sputtering yields, enhanced by more than an order of magnitude, have been observed for 80 keV Xe ion irradiation of monocrystalline Au nanorods. Yields are in the range 100–1900  atoms/ion compared with values for a flat surface of ≈50.
