Photoswitchable NIR‐Emitting Gold Nanoparticles [PDF]
Angewandte Chemie International Edition, 2016 AbstractPhoto‐switching of the NIR emission of gold nanoparticles (GNP) upon photo‐isomerization of azobenzene ligands, bound to the surface, is demonstrated. Photophysical results confirm the occurrence of an excitation energy transfer process from the ligands to the GNP that produces sensitized NIR emission.
