Abstract
The influence of iron and copper nanoparticles of different sizes on the physico-chemical processes occurring in colloidal solutions during laser breakdown has been investigated. The water dissociation occurring under the action of breakdown plasma is characterized by generation of hydroxyl radicals. It is found that both the material of nanoparticles and their size affect the processes of hydroxyl radical generation under the action of laser breakdown plasma.
