Fig. 4: Time-dependent UV–Vis spectra of the nanoclusters.
From: Interdependence between nanoclusters AuAg24 and Au2Ag41

Monodisperse AuAg24 is converted to (Au2Ag41)■(AuAg24) bi-nanocluster system in the presence of DPPM. Inset is the amplified photoelectron spectra, which suggest the formation of Au2Ag41 nanocluster.
