摘要
在室温下,采用射频磁控溅射法制备了Cu/TiOx纳米晶复合薄膜.利用X射线粉末衍射(XRD)、X射线光电子能谱(XPS)对其结构进行表征,并研究了Cu/TiOx复合薄膜的UV-vis吸收谱和亲水性.结果表明,退火前后薄膜中钛元素皆以Ti3+形式存在.薄膜在可见区有吸收,吸收限为600nm左右.Cu/TiOx复合薄膜具有良好的亲水性.这主要是由于Cu的掺杂,使得薄膜的性能的亲水性变好.
Cu/TiOx composite films have been deposited by RF magnetron sputtering at room temperature. The chemical components and structures of the Cu/TiOx composite films have been characterized by X-ray diffractometer （XRD）,X-ray photoelectron spectroscopy （ XPS）,UV-vis spectroscopy and water contact angel measurement. It is found that the titanium presents in the form of Ti3 ＋ before and after annealing. The results of UV-vis spectroscopy show the visible light absorption features of Cu/TiOx composite films with the absorption edge at about 600 nm. Contact angle results indicate that the Cu/TiOx films are hydrophilic,which is attributed to the added Cu.
