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.

Gold Nanoparticles as Absolute Nanothermometers [PDF]
Nano Letters, 2018 Nanothermometry is a challenging field that can open the door to intriguing questions ranging from biology and medicine to material sciences. Gold nanorods are excellent candidates to act as nanoprobes because they are reasonably bright emitters upon excitation with a monochromatic source. Gold nanoparticles are commonly used in photothermal therapy as
