Photoluminescence of the Au₃₈(SR)₂₆ nanocluster comprises three radiative processes.

ABSTRACT: Photoluminescence of ultrasmall, atomically precise gold nanoclusters constitutes an area of significant interest in recent years for both fundamental research and biological applications. However, the exploration of near-infrared photoluminescence of gold nanoclusters is still in its infancy due to the limitations of synthetic methods and characterization techniques. Herein, the photoluminescence properties of an Au₃₈(PET)₂₆ (PET = 2-phenylethanethiolate) nanocluster are investigated in detail. The Au₃₈(PET)₂₆ exhibits an emission peak at 865 nm, which is revealed to be a mix of fluorescence, thermally activated delayed fluorescence, and phosphorescence via the combined analyses of time-resolved and temperature-dependent photoluminescence measur
