【 摘 要 】

The synthesis of cobalt oxide nanoparticles capped with TOPO from the thermal decomposition of bis(N-cyclohexyl-1-naphthaldehydato)cobalt(II) complex is reported. The effect of decomposition temperature was investigated and sophisticated characterization techniques were used to characterize the complex and nanoparticles. The FTIR spectrum of the complex confirmed the formation of the precursor through the presence of the expected functional groups. The absorption and emission spectra showed an increase in wavelength when the synthetic temperature was increased. The XRD patterns of the nanoparticles displayed the formation of Co3O4 face-centred cubic structure. The formation of the metallic cobalt nanoparticles was also observed at higher temperature. TEM images of the cobalt oxide nanoparticles revealed spherical shaped particles.
