摘要/Abstract

摘要： 采用多元醇回流法，合成了组成可调的Zn_xCd_1-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Zn_xCd_1-xS 具有六方纤锌矿结构，粒径在5~20 nm左右，并且Zn_xCd_1-xS 呈现出随组成改变而连续调变的光学性质。

Abstract: The compositiontunable Zn_xCd_1-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 Zn_xCd_1-xS were studied by UVvis and photoluminescence (PL) spectroscopy. The results indicated that the Zn_xCd_1-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 Zn_xCd_1-xS compounds. Both the absorption and luminescence band systematically shifted from the longer wavelength for CdS to the shorter wavelength for ZnS.

Key words: Zn_xCd_1-xS, optical property, polylol refluxing
