Microstructure and Optical Properties of ZnO-doped CeO_2 Thin Films Using Sol-Gel Method

摘要

This paper describes microstructure and optical characteristics of ZnO-doped CeO_2 thin films were deposited by sol-gel method with various preheating and annealing temperatures. Particular attention will be paid to the effects of an annealing treatment in air ambient on the physical properties. The deposited films were characterized using X-ray diffraction. The surface morphologies of annealed film were examined by scanning electron microscopy. Optical properties of the ZnO-doped CeO_2 thin films were obtained by UV-visible recording spectrophotometer. The dependence of the optical properties and microstructure characteristics on thermal treatment was also investigated.
