论文摘要
我们研究了用强烈的飞秒激光脉冲引起的水血浆生成早期溶剂化电子的动力学。根据溶剂化电子的衰减动力学，溶剂化电子（Geminate重组）的快速重组过程的寿命（500 ps至1 ns）比以前的脉冲光解研究（10-100 PS）的寿命延长（500 ps至1 ns）。这种异常较长的寿命归因于由于激光诱导的血浆产生的丰富的自由电子的额外产生，这意味着游离电子对溶剂化电子动力学的显着影响。
We studied the dynamics of solvated electrons in the early stage of plasma generation in water induced with an intense femtosecond laser pulse. According to the decay kinetics of solvated electrons, fast recombination process of solvated electrons (geminate recombination) occurred with a more prolonged lifetime (500 ps to 1 ns) than that observed in previous pulse photolysis studies (10-100 ps). This unusually longer lifetime is attributed to additional production of solvated electrons due to abundant free electrons generated with the laser-induced plasma, implying significant influence of free electrons on the dynamics of solvated electrons.
