Abstract : Recently, aggregation-induced emission (AIE) properties have been revealed for some metal nanoclusters
(NCs), providing a new approach to improve the quantum yields (QY). In the present study, a two-stage
assembly was carried out between adenosine monophosphate capped bimetallic nanoclusters of gold
and silver (Au–AgNCs@AMP) and polyethylenimine (PEI), in which the QY was improved from 8.64% to
25.02%, showing obvious assembly induced emission enhancement (AIEE) properties. The intrinsic
mechanisms of the assembly and emission enhancement in two stages were studied in depth, which indicated
