摘要
Abstract
Cu doped ZnO nanoparticles were prepared by the sol-gel method in order to study the origin of room temperature ferromagnetism and optical properties of ZnO-based diluted magnetic semiconductors. X- ray diffractometry (XRD) shows that Zna-xCu+O samples are single phase with ZnO-like wurtzite structure. Znl-CuxO was ferromagnetic at room temperature, which ,attributed to the exchange interaction between the defects of zinc oxide and the doped Cu ions. All the samples show two distinct emissions, a sharp peak in the UV region and a broad deep level peak in the visible light regiom Cu doping into the ZnO lattice can effectively enhance the visible emission. Therefore, Znl-CuO system'may be a potential candidate in splntronics and photocatalytic.关键词
