摘要

We report on the functionalization of silicon oxide nanostructures using luminescent dye molecules and the characterization of these systems by optical microscopy. The nanostructures are prepared by local anodic oxidation (LAO) of a dodecyl-terminated silicon substrate using an atomic force microscope (AFM). The silicon oxide nanostructures are negatively charged and the cationic dye rhodamine 6G could be successively bound to the structures by electrostatic interactions. A quenching of luminescence due to the interaction of the excited states with the silicon was found. The luminescence signal is attributed to monomeric Rh6G molecules with a slight blue shift of the emission due to the changed chemical environment.
