Evaluating the quantum confinement effect of isolated ZnO nanorod single-quantum-well structures using near-field ultraviolet photoluminescence spectroscopy

Using low-temperature near-field spectroscopy of ZnO nanorod single-quantum-well structures, the dependence of the quantum confinement effect of the photoluminescence peak on the well width was observed and the homogeneous linewidth was determined as 3 meV.
