在水溶液中,常温常压下不加入任何催化剂,用电子加速器辐照作为一种新的方法可以成功制备出纳米银.我们利用XRD、TEM、UV、DSC来分别表征材料的结构、形貌、大小、光学特性以及材料的熔点.TEM图像证明颗粒大小为30nm,这与XRD实验通过Scherer理论公式计算的结果相一致.

A new electron beam method has been successfully developed to prepare silver nano-particles at roomtemperature and ambient pressure,without any kind of catalysts.The structure,morphology,size,optical propertiesand the melting point have been characterized by X-ray diffraction (XRD),transmission electron microscopy (TEM),ultraviolet-visible spectrophotometer (UV-vis) and differential scanning calorimeter (DSC) were utilized to characterize the product.TEM results show that the average size of silver nano-particles is about 3nm in agreement with thecalculated value size from XRD using Scherer formula.
