Surface Plasmon Resonances in Silver Nanostars [PDF]
Sensors, 2018 The recent development of silver nanostars (Ag-NSs) is promising for improved surface-enhanced sensing and spectroscopy, which may be further exploited if the mechanisms behind the excitation of localized surface plasmon resonances (LSPRs) are identified.
