A deep understanding on the luminescence property of aggregation‐induced emission (AIE) featured metal nanoclusters (NCs) is highly desired. This paper reports a systematic study on enhancing the luminescence of AIE‐featured Au NCs, which is achieved by Ag doping to engineer the size/structure and aggregation states of the Au I ‐thiolate motifs in the NC shell. Moreover, by prolonging the reaction time, the luminescence of the as‐synthesized AuAg NCs could be further tailored from orange to red, which is also due to the variation of the Au I ‐thiolate motifs of NCs. This study can facilitate a better understanding of this AIE‐featured luminescent probe and the design of other synthetic routes for this rising family of functional materials.
