文摘

At a low temperature of 450 C, ZnS nanoribbons have been synthesized on Si and KCl substrates by asimple chemical vapor deposition (CVD) method with a two-temperature-zone furnace. Zinc and sulfur powdersare used as sources in the different temperature zones. X-ray diffraction (XRD), selected area electron diffraction(SEAD), and transmission electron microscopy (TEM) analysis show that the ZnS nanoribbons are the wurtzitestructure, and there are two types-single-crystal and bicrystal nanoribbons. Photoluminescence (PL) spectrumshows that the spectrum mainly includes two parts: a purple emission band centering at about 390 nm anda blue emission band centering at about 445 nm with a weak green shoulder around 510 nm.
