Abstract:

We present the results of optical waveguiding of nanowires/quantum dots hybrid systems which were made by depositing CdTe quantum dots (QDs) on ZnO nanowires (NWs). We used a laser confocal/atomic force combined microscope to image the QD photoluminescence caused by the light propagation along the NW/QD hybrid systems, and the nanoscale topographic images of the samples. The propagation lengths of the samples were estimated and shown to be consistent with measured thickness of the samples.
