电沉积Co掺杂ZnO薄膜的光致发光及磁性研究
Photoluminescence and Magnetic Properties of Electrodeposited Co-doped ZnO Thin Films
摘要
Abstract
Co-doped ZnO films were fabricated by using electrodeposition method on the ITO substrates.X-ray diffraction (XRD) and scanning electron microscope (SEM) results indicate that Co-doping doesnt change the hexagonal wurtzite crystal structure of obtained ZnO films obviously.The photoluminescence spectra indicate that Co-doping cause the red-shift of the band gap.The magnetic properties of the films were investigated by VSM measurement at room temperature.The results indicate that 10% Co-doped ZnO thin film represents paramagnetism but 5% Co-doped ZnO thin film shows ferromagnetism, and the ferromagnetism is ascribed to the defects caused by Co-doping.关键词
