Abstract

Abstract : Incorporating anisotropic surface charges on atomically precise gold nanoclusters led to a intense shortwave infrared photoluminescence exceeding 1100 nm with QY up to 6.1%. Abstract : Incorporating anisotropic surface charges on atomically precise gold nanoclusters (Au NCs) led to a strong absorption in the near-infrared region and could enable the formation of self-assembled Au NCs exhibiting an intense absorption band at ∼1000 nm. This surface modification showed a striking enhancement of the photoluminescence in the Shortwave Infrared (SWIR) region with a quantum yield as high as 6.1% in water.
