摘要

研究了,60,Co γ射线辐照硝酸银水溶液体系制备纳米银粉。利用XRD、TEM、DSC、LSPSDA 分别表征了材料的物相、粒径、形貌、以及熔点。结果表明，表面活性剂（PCM）在0.6−2.2 g/100 mL 范围内，反应得到的纳米银粒子的粒径随浓度的增加而减小，纳米银粒子的熔点随着粒径的减小而减小。表面活性剂浓度为2.2 g/100 mL 时，粒径最小可达到19.9 nm，相应熔点为126.18℃。不同PH 值的辐照溶液所得产物均为单质银颗粒，银盐溶液的酸碱性对其辐照产物基本不产生影响。

Abstract

60,Co γ rays irradiation method was used to prepare nano-particle silver in aqueous solution. The structure, morphology, size and the melting point had been characterized by X-ray diffractometer (XRD), Transmission Electron Microscopy (TEM), and Differential Scanning Calorimeter (DSC). The results show that the size of gained particles decreases with increment of PCM concentration and the melting point becomes smaller with decrement of the particle size, while the concentration is changed from 0.6 g/100 mL to 2.2 g/100 mL. The smallest size of silver nano-particle is 19.9 nm, and the melting point is 126.18°C when the concentration is 2.2 g/100 mL. The pure silver nano-particles have been obtained at different pH. It is found that the pH of the aqueous solution has no effect on the constitution of the sample.
