【中文摘要】 以Zn Cl2 与硫代乙酰胺为原料,以span-80、tween-80为复合型表面活性剂,采用乳液法制备了纳米Zn S.用XRD技术研究了纳米Zn S的晶型结构,原子力显微镜测定其粒径,利用发射光谱对纳米微粒的光学性能进行了表征.实验结果证明,Zn S颗粒粒径在1 0~5 0 nm之间,并具有纳米材料所特有的量子尺寸效应 【英文摘要】 The paper presents the emulsion method with ZnCl_(2) and TAA as raw materials, and span-80、tween-80 as compound surface active agents and utilizes the a forementioned method to produce nanometer ZnS particles. The nanoparticles were studied using XRD, AFM and PL. The XRD shows that the particles are of cubic crystallites structure. Atom force microscope is used to obtain precise particle size distribution, and the result indicates that the size is in a range of 10 to 30nm. Emission spectrum has been elabora...
