Synthesis, characterization and room temperature photoluminescence properties of briers-like ZnO nanoarchitectures

Briers-like ZnO nanoarchitectures, which consisted of sword-like ZnO nanosheets, have been prepared by a facile organic CTAB (cetyltrimethylammonium bromide, CH3(CH2)15N+(CH3)3Br−) inducing deposition process on the titanium substrate. The nanostructured composite has been characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FTIR), and X-ray photoemission spectra (XPS). The XRD pattern indicates that the sward-like ZnO nanosheets are the high ordered nanolayered inorganic–organic composites. The ordered layered nanocomposite exhibits the room temperature photoluminescence (RTPL) characteristics. It is inferred that the RTPL of ZnO/CTAB ordered nanolayered composite might be induced by the interfacial effect between the ZnO and the surfactant CTAB.
