Abstract

In the present work, transparent conductive Zinc oxide (ZnO) thin films were deposited at constant radio-frequency (RF) power of 50W on indium tin oxide (ITO) coated polyethylene terephthalate (PET) substrates by varying deposition time. Structural, surface morphology and optical properties of films were studied by various analytical techniques like X-ray diffraction (XRD), Atomic force microscopy (AFM), Field emission scanning electron microscopy (FESEM) and Photoluminescence (PL). The structural properties studied by X-ray diffraction indicates that the films exhibited preferred c-axis oriented (002) phase of wurtzite structure perpendicular to the substrate. The roughness of films increases with increasing film thickness. The PL spectra showed a strong UV emission.
