Silver Nanoparticles Formation By Redox Reaction In Laser Treated Sodalime Glass

Abstract : We report on the formation of silver nanoparticles by intense ultraviolet laser exposure of silver-exchanged sodalime glass. The laser exposure leads to the formation of a molten glass phase in which a redox reaction occursbetween diffused oxygen form the atmosphere and the silver ions. The mechanism responsible for their formation is rather counterintuitive as oxygen acts as a very efficient reducer of the silver ions.
