Abstract

The in-situ interconversion of silver and silver oxide nanoparticles was achieved in ultrathin TiO2 films using hydrogen and oxygen plasmas as dry redox reagents. Absorption spectroscopy and transmission electron microscopy showed that the chemical transformation gave rise to narrowing of size distributions of both silver and silver oxide nanoparticles upon repeated interconversion.
