Abstract :
Using low-temperature near-field spectroscopy of isolated ZnO nanorod single-quantum-well structures (SQWs), the dependence of the quantum confinement effect of the photoluminescence peak on the well width was observed. Furthermore, the homogeneous linewidth of the isolated ZnO SQWs was determined as small as 3 meV.
