Plasmonic properties and stability of Au and Cu nanoparticles embedded in cerium oxide
Abstract
<jats:title>Abstract</jats:title><jats:p>With the aim of sensitizing cerium oxide—a very important catalytic material—to visible light, its coupling with Au and Cu nanoparticles is investigated. The samples are grown by physical synthesis by embedding a layer of nanoparticles between two cerium oxide films. The films are controlled in composition by <jats:italic>in-situ</jats:italic> x-ray photoemission spectroscopy and in morphology by <jats:italic>ex-situ</jats:italic> scanning electron microscopy. The optical properties as a function of the oxide thickness, investigated by spectrophotometry in the UV-Vis range, are interpreted based on the results of the morphological characterization and of simulations based on the Maxwell Garnett model. The stability of chemical and optical properties after air exposure is also investigated. The results, indicating that stable materials with tuneable optical properties can be obtained, are important in view of the potential application of the investigated systems in photocatalysis.</jats:p>
