摘要

In this paper, we report a facile solution-based route for the synthesis of bis-(8-hydroxyquinoline) cadmium (CdQ(2)) complex nanorods and nanoflowers (bundles of nanorods) in an oleic acid-sodium oleate-ethanol-hexane (or not)-H2O system at 55-100 degrees C. Field emission-scanning electron microscope (FESEM) images indicated that a longer time and a higher temperature would result in nanoflowers, while higer concentrations of the reactants and the surfactant with a lower temperature and a shorter reaction time would be appropriate for the formation of nanorods. Also, the hexane could sabotage the anisotropic crystal growth of the complex, leading to shorter nanorods. The C, H, and N element analysis and thermal gravimetric analysis (TGA) jointly determined the molecular formula of the products, and the Fourier-transform infrared spectrum (FTIR) was utilized to further confirm that the samples were made up of CdQ(2). All the samples possessed excellent photoluminescence (PL) properties. This facile methodology could be extended for the controlled large-scale synthesis of nanostructures of other functional complexes, and the obtained CdQ(2) nanorods could be introduced as the building blocks for novel optoelectronic devices.
