铬/磷二元团簇的形成和光解
Formation and Photodissociation of Chromium/Phosphorus Binary Clusters
摘要
Abstract
Chromium/Phosphorus binary clusters were produced by direct laser ablation and analyzed by tandem time-of-flight mass spectrometer. The main clusters formed were rich in phosphorus. There is an oscillation in CrP+m series(the peaks with even m are stronger than those with odd m, especially the peaks of CrP+4 and CrP+8 are the strongest) and this may be ascribed to the specific stability of P4 structure. There are some strong peaks such as Cr3P+8, Cr4P+9, Cr5P+11, Cr6P+12, Cr8P+14, etc., which dont change with the change of the ratios of Cr to P in the samples, and their stability could be explained with an electron model of valence electrons filling the d orbitals of Cr. The results of photodissociation just accord with the model.关键词
