Site-specific Surface Excitation of Calcium Oxide "Nanocubes"
EMSL Project ID
24391
Abstract
This proposal is a continuation of research under EMSL User Proposal #21596. The interaction between light and highly dispersed oxide materials is fundamentally important in photocatalysis, photoelectrochemistry, sensor technology, and microelectronics and materials processing. Furthermore, surface functionalization of nanocrystalline oxide materials can lead to unexpected optical properties and makes them promising candidates for inorganic phosphors. Finally, a variety of optical spectroscopies have been employed for the characterization of chemically reactive surface sites in the field of heterogeneous catalysis.As highly dispersed alkaline earth oxides (AEOs) exhibit many different local surface structures, their identification is a complex task. However, due to the ionicity and simple cubic structure, AEOs constitute a unique model system for surface science studies on insulating metal oxides.
