英文摘要 | the crystal structure of the [ag62s12(sbut)32](2+) nanocluster (denoted as nc-i) has been successfully determined, and it shows a complete face-centered-cubic (fcc) ag14 core structure with a ag-48(sbut)32 shell configuration interconnected by 12 sulfide ions, which is similar to the [ag62s13(sbut)32](4+) structure (denoted as nc-ii for short) reported by wang. interestingly, nc-i exhibits prominent differences in the optical properties in comparison with the case of the nc-ii nanocluster. we employed femtosecond transient absorption spectroscopy to further identify the differences between the two nanoclusters. the results show that the quenching of photoluminescence in nc-i in comparison to that of nc-ii is caused by the free valence electrons, which dramatically change the ligand to metal charge transfer (lmct, s 3p -> ag 5s). to get further insight into these, we carried out time-dependent density functional theory (tddft) calculations on the electronic structure and optical absorption spectra of nc-i and nc-ii. these findings offer a new insight into the structure and property evolution of silver cluster materials. |
