ZnO nanostructured thin films: Structural and optical properties controlled by ruthenium content

Abstract

Undoped and ruthenium doped ZnO films were prepared on glass substrate using sol-gel spin coating method. The optical and structural properties of the films were analyzed. The X-ray diffraction (XRD) measurements revealed that the films are formed from ZnO with a hexagonal wurtzite crystal structure. The Ru dopant content has not a effect on the crystallinity. The surface morphology of the ZnO films was found to depend on the Ru dopant content. Other properties such as refractive index, extinction coefficient, and volume and surface energy loss were calculated using spectrophotometric measurements. © 2014 Elsevier B.V. All rights reserved.
