The redox reaction took place in this system and the final products CuI were obtained. It′s found that the morphology of CuI could be influenced a great deal by the experimental parameters such as w0 (the molar ratio of water to surfactant), reactant concentration and the aging time. Hexagonal or shuttle like CuI flakes, nanoparticles and nanofibers could be prepared respectively under certain conditions.展开更多

The influence of iodine doping concentration in acetonitrile solution on the structure, topographic and optical properties of CuI thin films was investigated. X-ray diffraction results showed that CuI iodine-doped films doped CuI：I2 were in γ-phase of zinc blende structure with （111） preferential plane. Scanning electron microscopy revealed that the microstructure of CuI films depended on the relative amount of doping iodine in the solution. When the iodine doping amount in acetonitrile solution was 0.025 g, the film was uniform and compact, the optical transmittance was 75.4% in the part of visible region and the energy band gap was close to 2.96 eV.展开更多
