摘要/Abstract

摘要： 采用电化学恒电位沉积方法在ITO导电玻璃上和在ZnO薄膜上沉积氧化亚铜(Cu₂O),并通过X射线衍射(XRD)和扫描电镜(SEM)对晶体的微观结构和表面形貌进行了分析.在ZnO基底上沉积得到了纳米级的Cu₂O粒子并且具有明显择优取向,而在ITO导电玻璃上仅得到粒径为2—5μm的Cu₂O粒子,没有明显的择优取向.对薄膜的生长机理进行了讨论.

关键词: 氧化亚铜, 电沉积, 薄膜, 氧化锌

Abstract: The copper(Ⅰ) oxide(Cu₂O) films were grown on ITO and ZnO substrate by electrochemical potentiostatic deposition.The surface morphology and the structure of the films were investigated by X-ray diffraction(XRD) and scanning electron microscopy(SEM).The nanocrystalline Cu₂O grains have been formed on ZnO substrate with a preferential orientation,while the grain size for films grown on ITO ranges from 2 to 5 μm without a preferential orientation.The growth mechanism of the films is discussed.

Key words: cuprous oxide, electrodeposition, thin films, zinc oxide
