Abstract

Previous experiments have demonstrated that photoluminescence properties, both excitation and emission spectra, of powdered MgO depend strongly on the powder preparation and treatment. Similar dependencies have been found for CaO, SrO, and BaO powders. The observed broad photoemission bands have been attributed to the low-coordinated surface sites. Recent advances in nanoscale science and technology have made it possible to produce nearly monodispersed alkaline-earth oxide nanoparticles of very high surface area and investigate their optical properties in details. Here we present the results of our theoretical and experimental work in this area and present new results. ©The Electrochemical Society.
