    摘要:

    用電化學沉積方法制備出了Nd摻雜的ZnO薄膜，并研究其結(jié)構(gòu)和光學性質(zhì)。X-射線衍射譜的結(jié)果表明Nd3 替代Zn2 進入到ZnO晶格中，并沒有引起雜相的出現(xiàn)。吸收譜的分析表明，隨著摻雜濃度的增大，吸收峰向短波長方向移動 ，即發(fā)生藍移。光致發(fā)光譜的結(jié)果表明隨著Nd3 摻雜濃度的增大，紫外峰強度減小，可見光部分強度增大了。

    Abstract:

    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.
