Abstract / Bemerkung
In this paper, nanocrystalline cerium dioxide (CeO2) thin films with thicknesses of 41-334 nm were grown on glass substrates at 450 degrees C by pulsed spray-evaporation chemical vapor deposition (PSE-CVD). Through changing the film thickness, the texture and the band gap energy of CeO2 were altered in a wide range, which implies promising applications in microelectronics, optoelectronics and photocatalysis. X-ray diffraction (XRD) shows that all films grown by this process crystallize in the cubic structure, however, evident changes in the preferred orientation were found when increasing the film thickness. Atomic force micrographs of a 334-nm-thick film indicate a very uniform surface morphology composed of a sub-micrometer sized taper-like structure. Optical measurements show high transparency for all films and reveal a systematic change in the band gap energy with the film thickness. (C) 2009 Elsevier B.V. All rights reserved.
