Abstract EN
The oriented (002) ZnO films were grown on a- and c-face sapphire by pulsed laser deposition.
The X-ray diffraction analysis revealed that the oriented (002) ZnO films were epitaxially grown on the substrate successfully.
The sample on a-face sapphire had higher crystal quality.
However, the photocatalytic activity for Rhodamine B degradation of ZnO film on c-face sapphire was higher than that on a-face sapphire.
The Raman spectrum and XPS analysis suggested that the sample on a-face sapphire had higher concentration of defects.
The result of the contact angle measurement revealed that the sample on c-face sapphire had higher surface energy.
And the investigation of the surface conductance implied that the higher light conductance was helpful for the photocatalytic activity.
