我们研究了CO/O2/Pt(111)表面的飞秒化学反应。在10 μJ/mm ~ 2以下,产额与注量呈线性关系。在10 μJ/mm ~ 2以上,产额随注量呈非线性变化。从量子产额对波长的依赖关系,我们确定非线性表面飞秒化学是由非热衬底电子的影响。
We studied the surface femtochemistry of CO/O2/Pt(111) induced with 0.3 ps laser pulses over a wide range of wavelength and fluence. Below 10 μJ/mm2, the yields depend linearly on fluence. Above 10 μJ/mm2, the yields scale nonlinearly in the fluence. From the dependence of the yields on wavelength, we determine that the nonlinear surface femtochemistry is influenced by nonthermal substrate electrons.
