摘要: 采用多元醇回流法,合成了组成可调的ZnxCd1-xS 纳米材料,采用透射电镜(TEM)及X射线粉末衍射(XRD)表征了样品的结构特征,并通过紫外可见吸收(UVVis)和光致发光(PL)光谱对样品进行了光学性质的研究。文章所用的合成方法具有简单、快速、经济、条件温和等特点,所得ZnxCd1-xS 具有六方纤锌矿结构,粒径在5~20 nm左右,并且ZnxCd1-xS 呈现出随组成改变而连续调变的光学性质。

Abstract: The compositiontunable ZnxCd1-xS compounds were prepared by a facile and mild approach involved in polylol refluxing processes. Their structures were characterized using X-ray diffraction (XRD) and transmission electron microscope (TEM) analyses. The optical properties of ZnxCd1-xS were studied by UVvis and photoluminescence (PL) spectroscopy. The results indicated that the ZnxCd1-xS compounds exhibited as the wurtzite structure and their particle size decreased with the increase of Zn content. The compositiondependence optical properties were observed for all ZnxCd1-xS compounds. Both the absorption and luminescence band systematically shifted from the longer wavelength for CdS to the shorter wavelength for ZnS.

Key words: ZnxCd1-xS, optical property, polylol refluxing
