以硝酸铜Cu(NO3)2·3H2O、硝酸铬Cr(NO3)3·9H2O、硝酸铋Bi(NO3)3·3H2O和乙二醇为原料,利用溶胶-凝胶工艺在石英衬底上制备了纳米Cu2Bi2Cr2O8薄膜。通过X射线衍射(X-Ray Diffraction, XRD)和拉曼测试对样品进行了表征。结果表明,Cu2Bi2Cr2O8薄膜具有良好的光学特性,其禁带宽度为1.49 eV; 在磁性测试方面,Cu2Bi2Cr2O8薄膜呈现出了良好的铁磁性。

Taking Cu(NO3)2·3H2O, Cr(NO3)3·9H2O, Bi(NO3)3·3H2O and ethylene glycol as raw materials, Cu2Bi2Cr2O8 thin films were fabricated on SiO2 substrates by a sol-gel process. The thin film samples were characterized by X-ray Diffraction (XRD) patterns and Raman tests. The results showed that the Cu2Bi2Cr2O8 thin films had good optical properties. Their band gap was 1.49 eV. In the magnetic hysteresis (M-H) loop measurements, the Cu2Bi2Cr2O8 thin films showed their excellent ferromagnetism.
