Zusammenfassung:In this paper, ZnxCd1-xS nanocrystals (NCs) were directly immobilized on graphene nanoribbons (NRs) by a facile one-step reaction. During the reaction, the formation of NCs and the reduction of graphene oxide to graphene NRs occurred simultaneously and the value of x could be adjusted by controlling the molar ratio of Zn and Cd precursors. The facts were confirmed by X-ray diffraction (XRD), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR). Moreover, Ultraviolet-visible (UV-vis) absorption spectroscopy data indicate that the absorbance of the nanocomposites can be successfully tuned from 319 to 583nm, making them a great promise for wide potential applications in optoelectronics.
