采用CS-400型射频磁控溅射仪在Si(111)和石英基底上成功的制备了Zn1-xCuxO薄膜,薄膜的晶体取向和表面形貌用X射线衍射(XRD)仪和扫描电子显微镜(SEM)进行测量。利用紫外-可见光(UV-vis)分光光度计来测量基片为石英的Zn1-xCuxO薄膜的透射光谱。实验表明,采用射频磁控溅射制备的掺Cu氧化锌薄膜具有(002)峰的择优取向。随着Cu掺入量的增加样品成膜质量降低,禁带宽度减小,透射率下降。
Zn1-xCuxO films were prepared by the radio frequency magnetron sputtering technique(RF)on Si(111) and quartz glass substrates.The effect of Cu-doping on the structural and optical properties of ZnO films were discussed in details.X-ray diffraction(XRD) pattern indicates that the films are single phase and had wurtzite structure with c-axis orientation.The SEM shows that with the increasing of Cu content the grain size of ZnO films decreases and quality of ZnO films declines.In the transmittance spectra of the Zn1-xCuxO films the width of optical energy band gap and the transmittance are decreased with the increase of Cu content.
