The coupling of rare-earth elements with surface plasmon polaritons can lead to a change of their emission properties. We implant rare-earth elements in a nanometric silica spacer on top of an aluminum layer by ion beam implantation. The luminescence properties of such systems were examined by photo- and cathodoluminescence measurements. Placing zinc oxide nanowires on top of this two-layer system allows for additional coupling with surface plasmon polaritons, which generate a high electric field density in the spacer layer. The respective effects and the possibilities of tailoring the emission will be discussed.
