英文摘要	Metal nanoclusters have emerged as promising near-infrared (NIR)-emissive materials, but their room-temperature photoluminescence quantum yield (PLQY), especially in solution, is often low (<10%). We studied the photophysics of Au-22((BuPhC)-Bu-t equivalent to C)(18) (Au-22) and its alloy counterpart Au16Cu6((BuPhC)-Bu-t equivalent to C)(18) (Au16Cu6) (where Bu-t is tert-butyl and Ph is phenyl) and found that copper (Cu) doping suppressed the nonradiative decay (similar to 60-fold less) and promoted intersystem crossing rate (similar to 300-fold higher). The Au16Cu6 nanocluster exhibited >99% PLQY in deaerated solution at room temperature with an emission maximum at 720 nanometers tailing to 950 nanometers and 61% PLQY in the oxygen-saturated solution. The approach to achieve near-unity PLQY could enable the development of highly emissive metal cluster materials.
