Abstract

Gelatine has been employed to modify the growth of ZnO in a chemical bath deposition (CBD). The polymer profoundly affects crystal growth and leads to films of high-density which are composed of vertically aligned hexagonal ZnO microplatelets. This morphology is in stark contrast to the [0 0 0 1] orientated rods most often seen in CBD. These crysatllites are well defined, relatively uniform in diameter, thickness and shape. The height of the ZnO platelet in the film is ∼2.0 μm (as is the measured film thickness). The films present near perfect linear current-voltage (I-V) curves and have a very characteristic Raman resonance. Near band-edge emssion is observed in the low temperature photoluminescence (PL). © 2011 Published by Elsevier B.V. All rights reserved.
