Abstract
The angular dependent photoluminescence from ZnO nanorod array was investigated. Variations in the excitation and detection angles provided to reveal a blue shift and then splitting of a near-band edge emission into two bands. It is suggested that the observed phenomenon is caused by an inhomogeneous distribution of the emission along the nanorod length. The spatially resolved cathodoluminescence measurements confirmed that indeed the emission along the length of the nanorod is inhomogeneous and the top and bottom parts of the nanorod exhibit different emission spectra.
