A strong enhancement of the SWIR emission band at 1200 nm was observed when measuring in different local environments: in solution, in polymer composites, and in solids. SWIR in vivo imaging of mice assisted by deep learning after intravenous administration of these gold nanoclusters provides high definition pseudo-3D views of vascular blood vessels. %G English %2 https://cnrs.hal.science/hal-03740197/document %2 https://cnrs.hal.science/hal-03740197/file/HAL-ms.pdf %L hal-03740197 %U https://cnrs.hal.science/hal-03740197 %~ INSERM %~ UGA %~ CNRS %~ UGA-EPE
