Structure and Optical Properties of Electrodeposited Nd-Doped ZnO Thin Films

Nd-doped ZnO thin films have been prepared by an electrodeposition method. The structure and the optical properties of the films were investigated. X-ray diffraction spectroscopy analysis indicates that the Nd doping can not disturb the structure of ZnO. No additional peaks are observed in the samples. The optical absorption spectra of Nd-doped ZnO thin films show that the absorbance peaks of the samples shift towards short wave length with the increase of Nd doping concentration. The photoluminescence spectra show that with the increase of concentration of Nd3+, visible emission is enhanced greatly and the intensity of ultraviolet emission is reduced.
