Properties of CdS nanoparticles dispersed zirconia films

Zirconia films incorporated with cadmium sulfide semiconductor nanoparticle s were synthesized with the dip-coating technique in air. Amorphous and tra nsparent films were gained on the glass substrate. ZrO2: CdS films were cha racterized by X-ray diffraction (XRD), transmission electron microscopy (TE M), atomic force microscopy (AFM), optical absorption/fluorescence spectra. The size control of CdS particles was studied. The different morphology of ZrO2 and ZrO2: CdS films were observed. The blue shift of absorption band of CdS and its fluorescence properties are discussed. (C) 2001 Acta Metallu rgica Inc. Published by Elsevier Science Ltd. All rights reserved.
