摘要:

定量可靠的原子对分布函数(PDF)已获得纳米材料在一个简单的方式从一个标准的实验室透射电子显微镜(TEM)。这种方法看起来非常有希望使电子衍生的PDF(ePDF)成为表征纳米材料的常规步骤,因为这种TEM在化学和材料实验室中无处不在。显微镜上不需要特殊附件,如能量过滤器。描述了获得ePDF的方法以及该方法的一些机会和局限性。

英文摘要:

Quantitatively reliable atomic pair distribution functions (PDFs) have been obtained from nanomaterials in a straightforward way from a standard laboratory transmission electron microscope (TEM). The approach looks very promising for making electron-derived PDFs (ePDFs) a routine step in the characterization of nanomaterials because of the ubiquity of such TEMs in chemistry and materials laboratories. No special attachments such as energy filters were required on the microscope. The methodology for obtaining the ePDFs is described as well as some opportunities and limitations of the method.
