Abstract: Advances in the development of functional metal oxide particle systems for optical, electronic and photochemical applications rely on comprehensive characterization work which is based on a close connection between particle synthesis, materials’ characterization and physico-chemical in-depth experiments. We explored the effect of solid-solid interfaces inside pure and blended metal oxide nanoparticle systems [1] on the spectroscopic and photoelectronic ensemble properties using electron paramagnetic resonance, FT-IR and other optical spectroscopy techniques. Examples for firmly established structure-property relationships will be presented for particle networks of semiconducting oxides (TiO2, SnO2, ..) but also for insulating metal oxide materials like MgO nanocube powders.[2]
