为了扩大可以通过湿化学途径获得的高质量纳米半导体材料的范围，在水溶液中使用2-巯基乙醇和1-硫代甘油作为稳定剂制备了一系列氧化稳定的CdTe纳米团簇，其具有窄的尺寸分布和极小的粒径范围从1.3至2.4 nm。通过紫外-可见吸收光谱、光致发光光谱、X射线衍射、高分辨透射电子显微镜和X射线能量色散分析等手段对样品进行了表征。
In order to expand the range of high-quality nanosized semiconductor materials that can be obtained as quantum dots through a wet chemical route a series of oxidize-stable CdTe nanoclusters with narrow size distributions and extremely small particle sizes ranging from 1.3 to 2.4 nm has been prepared in aqueous solution using 2-mercaptoethanol and 1-thioglycerol as stabilizers. II has been investigated by means of UV-vis absorption and photoluminescence spectroscopy, X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and energy dispersive x-ray analysis (EDX).
