Femtosecond surface photochemistry: what is the role of the substraste electrons?, at Femtochemistry: The Lausanne Conference (Lausanne, Switzerland), Thursday, September 7, 1995
We studied the femtosecond laser-induced desorption of O2 and production of CO2 from a CO/O2/Pt(111) surface at 90K. The reaction pathway with 0.3-ps laser pulses is very different from that with nanosecond or continuous wave irradiation.[1,2] Our experiments address both the excitation excitation mechanism and the chemical pathway leading to O2 desorption and CO2 production using femtosecond laser pulses. When the fluence is below 10 µJ/mm2 the yields of O2 and CO2 vary linearly with laser fluence. Above 10 µJ/mm2 the yield is highly nonlinear in the fluence. The transition indicates a...
