Key Points

The aim is to characterize the photoluminescence properties of gold-doped nanoclusters.
Steady-state photoluminescence spectroscopy was utilized.
Time-resolved photoluminescence spectroscopy was applied.
Different metal compositions (Ag, Au, Pt, Pd, Ni) were examined.
Gold doping significantly enhances near-infrared luminescence.
Emission from these nanoclusters is predominantly attributed to phosphorescence.

Abstract

A series of MAg 24 (SR) 18 n − are characterized by steady-state and time-resolved photoluminescence spectroscopies. Gold doping significantly enhances the near-infrared luminescence, and the emission is revealed to be predominantly phosphorescence.
