The current knowledge on oxide materials affirms that most of their physico-chemical properties display acute size dependence. The size effects in oxide physics have frequently two interconnected faces, size-defect or non-stoichiometry effects and stmctural quantum-size. Key contributory factors include quantum confinement of electrical carriers within nanoparticles, charge and efficient energy transfer over nanoscale distances and in many systems a highly enhanced role of interfaces. With the growing technology of nano materials, it is necessary to understand the detailed basis for nanophotonic properties. Physico-chemical properties are mostly related to the industrial use of oxides such as ceramics, sensors, absorbents and/or catalysts. Novel application within these fields relies on the size-dependence of the optical and electronic transport properties of oxide nanomaterials.
