Study on Ferramagnetic Properties of Cu Doped ZnO
Abstract:We report a simple chemical vapor deposition method for producing a copper-doped ZnO hemispherical shell structure with room temperature ferromagnetism. By changing the growth temperature and the reaction time of a series of control experiments，We observed that the evolution of the global disconnect bomb-shaped structure forms a part of the product，And at different temperatures hemispherical steel shell hemispherical shell extension of reaction time together. Growth mechanism of ZnO: Cu hemispherical shell structure has been proposed is directed to the Cu-Zn-doped sphere, surface oxidation, and synthesized from the broken shell of zinc sublimation. Structural and optical properties of zinc oxide: X-ray diffraction, Raman spectroscopy and photoluminescence measurements show that Cu ions are successfully substituted into the position of Zn 2+ and more inherent structural defects. We believe that the combination of spectral analysis, magnetic copper content of the sample from the enhancement and oxygen vacancies increase.
