Abstract: ZnO-CNTs nanocomposites were successfully synthesized by sol method using Zn(CH3COO)2•2H2O and treated multiwalled carbon nanotubes (CNTs) as raw materials and diethyleneglycol (DEG) as regent. The samples were determined by means of X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), infrared (IR) absorbence, and photoluminescence (PL) spectrum. TEM and SEM images indicated that the coating layer was composed of ZnO nanoparticles with size less than 25 nm. The effects of various experimental conditions, such as reaction duration and reaction temperature on the obtained composites were investigated as well. Finally, PL function and possible formation mechanism of ZnO-CNTs nanocomposites were proposed. The PL spectra of ZnO-CNTs nanocomposites showed obvious blue-shifts compared with that of pure ZnO nanomaterial.
