Abstract
Spatially and spectrally resolved photoluminescence imaging of individual ZnO/ZnMgO nanorod single-quantum-well structures (SQWs) with a spatial resolution of 55 nm was performed using the optical near-field technique with a metallized UV fiber probe. Using excitation power density-dependent photoluminescence spectra of a ZnO/ZnMgO SQW nanorod, we observed the discrete energy levels in a ZnO quantum-well layer.
