结合脉冲放电气体束和激光溅射技术,开发了一套产生气相金属化合物分子和离子的装置。利用飞行时间质谱测试了金属铜靶与不同气体反应的离子产物和效率,并利用激光诱导荧光光谱方法测量了自由基分子产物的状态。测试结果表明,该装置可有效产生气相金属化合物自由基分子和离子,而且产物转动温度低,为下一步开展高精度金属化合物分子自由基电子态激光光谱研究打下了基础。

We have developed a setup that could produce gas phase metal compound molecules and ions by discharging assisted laser ablation.The ionic and neutral radical products have been investigated by the time-of-flight mass spectroscopy(TOF-MS)and laser-induced fluorescence spectroscopy(LIFs),respectively.The results showed that this setup could produce gas phase metal compound radical molecule ions with a high yield and low temperature.The refore,this source may help researchers in laser spectroscopic research on metal compound molecules.
