电化学沉积Nd掺杂ZnO薄膜的结构和光学性质的研究

用电化学沉积方法制备出了Nd掺杂的ZnO薄膜，并研究其结构和光学性质。X-射线衍射谱的结果表明Nd3 替代Zn2 进入到ZnO晶格中，并没有引起杂相的出现。吸收谱的分析表明，随着掺杂浓度的增大，吸收峰向短波长方向移动 ，即发生蓝移。光致发光谱的结果表明随着Nd3 掺杂浓度的增大，紫外峰强度减小，可见光部分强度增大了。

Structural and optical properties of electrodeposited Nd-doped ZnO thin films

In this study, Nd-doped ZnO thin film has been prepared by electrodeposition method. The structural and optical properties of the samples were investigated. X-ray diffraction spectroscopy analyses indicate that the Nd doping can not disturb the structure of ZnO. No additional peaks are observed in the samples and Nd3 substitute for Zn2 without changing the wurtzite structure. The optical absorption spectra of Nd-doped ZnO thin films indicate that with Nd doping concentration increases, the absorbance peaks of the samples shift towards short wave length. The photoluminescence spectra show that with the concentration of Nd3 increasing, visible emission enhanced greatly and the intensity of ultraviolet emission is reduced.
