摘要：

In this work, the luminescence of Au2Cu6 nanoclusters was controlled by tailoring the ligand to metal charge transfer via engineering the phosphine ligands with electron-donating or -withdrawing substituents. The fluorescence intensity was significantly enhanced from the Au2Cu6 nanocluster with P(Ph-F)(3) ligands (quantum yield QY = 5.7%) to that with P(Ph-OMe)(3) ligands (QY = 17.7%). In addition, the fluorescence of Au2Cu6 protected by P(Ph-OMe)(3) slightly red-shifts compared to that of Au2Cu6 protected by P(Ph-F)(3), which is similar to the trends of UV-vis spectra tendency.
