反应性物种在表面的等离子体处理中起重要作用，包括聚合物、金属、水和活组织。为了阐明表面反应机理，测量每种类型的反应物种对表面处理的影响是至关重要的。因此，我们先前开发了一种方法，以选择性地供应OH或O自由基到放置在室内空气中的表面。用真空紫外灯照射流过石英管的Ar/H2O或Ar/O2气体，使H2O和O2发生光解离，生成OH和O产生的气体从管端流到表面。然而，供应到表面的O密度仅约为
Reactive species play important roles in plasma treatments of surfaces, including polymers, metals, water, and living tissues. To elucidate the surface reaction mechanism, it is crucial to measure the effect of each type of reactive species on the surface treatment. Accordingly, we previously developed a method to selectively supply OH or O radicals to a surface placed in room air. Ar/H 2 O or Ar/O 2 gas flowing through a quartz tube is irradiated with a vacuum ultraviolet lamp, causing photodissociation of H 2 O and O 2 to produce OH and O. The resulting gas flows to the surface from the tube end. The O density supplied to the surface, however, is only approximately
