英文摘要Aluminum and aluminum-doped clusters have gained much attention in cluster science due to their potential applications in nanotechnology. Here, we report a combined photoelectron spectroscopy and density functional theory study of V-doped aluminum clusters. The lowest-energy geometric structures of neutral and anionic AlnV0/- (n = 5-14) clusters are identified by comparing the theoretical photoelectron spectra with the experimental results. Our results reveal that ground-state structural evolution of neutral and anionic clusters follows different patterns. The V atom in neutral AlnV- clusters moves from convex capped to surface-substituted, to encapsulated site at n = 12, and then returns to surface-substituted sites again. However, as for the anionic AlnV-, the metal V atom always occupies the convex capped sites with the cluster size increasing to n = 14. The most stable structure of Al14V- cluster possesses a C-3v symmetric cagelike structure with the highest occupied molecular orbital-lowest unoccupied molecular orbital gap of 1.52 eV. Molecular orbital and adaptive natural density partitioning analysis of Al14V- suggests that the peripheral Al-Al interactions and delocalized Al-V interactions play important roles in its structural stability.
