Abstract :
The optical properties of ZnO/ZnMgO multiple-quantum-well (MQW) nanorods were investigated by the optical near-field technique. Using a thin metal coated UV fiber probe, we performed spatially- and spectrally-resolved photoluminescence imaging of individual ZnO/ZnMgO MQW with a spatial resolution of 40 nm. Furthermore, we observed an anti-correlation feature in the PL intensity distributions. This is attributed to an optical near-field energy transfer in closely spaced pairs of ZnO/ZnMgO MQW nanorods.
