Self-assembled ZnO1-xSx nanorod arrays with varied luminescent and electronic properties

Vertically aligned and uniform ZnO1-xSx NRs with blue-green luminescence were obtained on glass using the hydrothermal method. The ratio of the blue to green luminescence intensities increases with thiourea doping and the positions of the luminescence peaks are red-shifted. At high doping concentration of thiourea, phase and morphology separations lead to formation of NR arrays with varied luminescent and electronic properties. The vertical ZnOS NRs p-n junctions could be self-assembled as indicated by SEM measurements in a through-the lens secondary electron mode. (C) 2015 Elsevier B.V. All rights reserved.
