Nanocomposite particles made of an oxide core and a polymer shell, or of an oxide core, a lumophore interlayer and a protecting polymer shell on the outside, exhibit remarkable luminescence properties. In the first case luminescence is generated by the absorption of UV-quanta in the ceramic core and transmission to the interface ceramic/polymer where carbonyl-groups are responsible for luminescence. In the latter case the luminescence is due to the interaction between lumophore, ceramic, and polymer, respectively. With this concept it is possible to realise materials with combined properties, such as super-paramagnetic luminescent nanoparticles.
