用飞行时间质谱法研究了激光直接溅射 Ｍｎ／Ｓｅ混合样品产生的二元团簇、团簇的光解行为及溅射ＭｎＯ２／Ｓｅ和 Ｍｎ／ＳｅＯ２样品产生的团簇正负离子．在 Ｍｎ－Ｓｅ二元团簇中，（Ｍｕｓｅ）ｎ＋是正离子的主要组分，［（Ｍｕｓｅ）ｎＳｅ］－是负离子的主要组分．当ｎ<５时，（Ｍｕｓｅ）ｎ＋的紫外光解有多种通道； ｎ≥５时光解以剥落ＭｕＳｅ方式进行．激光直接溅射 ＭｎＯ２／Ｓｅ， Ｍｎ／ＳｅＯ２两种体系产生的正负离子极为相似，符合团簇的气相聚合生长机理．正离子中（Ｍｎｏ）ｎ＋是主要组分，负离子中Ｓｅｎ－，（ＳｅＯ）－和（ＳｅｎＯ３）－是主要组分．
The time-resolved mass spectra of binary clusters, cluster photolysis and sputtered MnO2 / Se and Mn / SeO2 samples produced by laser direct sputtering were studied. In the Mn-Se binary cluster, (Muse) n + is the main component of the positive ion, [(Muse) nSe] - is the main component of the negative ion. When n <5, (Muse) n + has many kinds of channels for UV photolysis. When n≥5, the photolysis takes place in the MuSe mode. The direct and sputtered MnO2 / Se and Mn / SeO2 systems produce very similar positive and negative ions, which is in good agreement with the gas-phase polymerization growth mechanism of the clusters. Positive ions (Mno) n + is the main component, negative ions Sen -, (SeO) - and (SenO3) - is the main component.
