用飞行时间质谱仪研究了激光直接溅射Ag/O/S, Ag/O/Se, Ag/S/Se三元样品产生的二元、三元团簇. 主要产物分布特征为: 在直接溅射Ag/O/S三元样品的实验中, 主要探测到Ag/S二元团 簇; 在直接溅射Ag/O/Se三元样品的实验中, 主要探测到Ag/Se二元团簇; 在直接溅射Ag/S/Se三元样品的实验中, 主要探测到Ag/Se二元团簇和Ag/S/Se三元团簇. 利用激光串级溅射反应装置研究了Ag/O(S,Se)二元团簇和Se(S)一元团簇的反应. 实验表明, Se团簇能拆开Ag/S团簇和Ag/O团簇, S团簇能拆开Ag/O团簇. 以上实验事实表明元素间结合成簇的能力顺序是Ag/Se＞Ag/S＞Ag/O. 理论计算的结果也与此相符. 造成这种现象的原因被认为是成簇元素极化能力的不同对团簇稳定性造成了影响.
The binary and ternary clusters generated by laser direct sputtering Ag / O / S, Ag / O / Se and Ag / S / Se ternary samples were studied by time-of-flight mass spectrometry.The main products were characterized by direct sputtering Ag / S binary clusters were mainly detected in Ag / O / S ternary samples. Ag / Se binary clusters were mainly detected in the direct sputter Ag / O / Se ternary samples In Ag / S / Se ternary samples, the Ag / Se binary clusters and the Ag / S / Se ternary clusters were mainly detected.The effects of Ag / O (S, Se) binary clusters and Se (S) univalent clusters. The experimental results show that the Se clusters can disassemble Ag / S clusters and Ag / O clusters. The above experimental facts show that the order of the ability of the elements to cluster into clusters is Ag / Se> Ag / S> Ag / O. The result of the theoretical calculation is consistent with this. The reason for this phenomenon is considered as cluster elements The difference in polarization has an impact on the stability of the cluster.
