在450℃的低温下，采用简单的化学气相沉积(CVD)方法，在双温区加热炉中，在硅和氯化钾衬底上制备了硫化锌纳米带。在不同的温度范围内使用锌和硫粉作为源。X射线衍射仪、选区电子衍射仪和透射电子显微镜分析表明，所制备的纳米带为纤锌矿结构，分为单晶和双晶两种类型。光致发光(PL)光谱表明，该光谱主要由两部分组成：以约390 nm为中心的紫色发射带和以约445 nm为中心的蓝色发射带，在510 nm附近有一个微弱的绿肩。
At a low temperature of 450 degrees C, ZnS nanoribbons have been synthesized on Si and KCl substrates by a simple chemical vapor deposition (CVD) method with a two-temperature-zone furnace. Zinc and sulfur powders are 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 wurtzite structure, and there are two types-single-crystal and bicrystal nanoribbons. Photoluminescence (PL) spectrum shows that the spectrum mainly includes two parts: a purple emission band centering at about 390 nm and a blue emission band centering at about 445 nm with a weak green shoulder around 510 nm.
