ScholarBank@NUS Repository. https://doi.org/10.1016/j.diamond.2012.02.018 | Abstract: | Zinc oxide/diamond-like carbon (ZnO/DLC) nanocomposite films were grown using two different composite targets, namely zinc/carbon (Zn/C) and zinc oxide/carbon (ZnO/C) targets with pulsed laser deposition technique as a comparison. In both cases, transmission electron microscopy (TEM) confirmed that ZnO nanoclusters were formed embedded in an amorphous carbon matrix. Interestingly, only films obtained from ZnO/C targets yielded monochromatic UV (∼378 nm) emission peaks in photoluminescence. X-ray photoelectron spectroscopy (XPS) revealed that a higher fraction of O 2- ions in oxygen-rich ZnO was formed in ZnO/DLC films prepared by ZnO/C targets but with a consistently lower sp 3 content. As such, the hardness of the films decreased. However, the formation of SiC due to the deposition process improved the adhesion strength of the films, as evidenced by experimental data. © 2012 Elsevier B.V.
