最常用靶材为Cu,其他有 Mo, Fe, Ni, Co, Cr, Ag, W等。 XRD衍射图谱直观反应的信息是衍射峰强,峰位,缝宽,但其影响因素诸多,衍射谱的任何信息的变化都不是单因素的影响,如下图: 粉末XRD制样时特别注意:首先样品无明显大颗粒,即手摸有“面粉”手感,一般粒径应该在10um最佳,另外在制样时XRD载玻片样品槽...
按照如下过程打开前面精修得到的.prf文件,得到精修后的图谱。 然后点击File-save data as-save data as XYY files,勾选全部,点击ok,选择要保存的文件位置,这样便导出了.XYY文件了。 将.XYY文件直接拖入Origin即可作图,最终作图如下: 两相精修 以富锂锰基LiMO2+Li2MnO3正极材料为例 两相精修与单相精修精修过程类...
A series of Pd-Ag composite membranes with different stoichiometry were prepared and average lattice spacings were measured from the XRD pattern, as plotted in Fig. 3. It can be seen that the average lattice spacing increases with the fraction of silver. The relation of Fig.3 can be used ...
whereλis the X-ray wavelength (0.15406 nm for Cu),θis the Bragg angle of the diffraction peak, and B is the full-width-half-maximum (FWHM) of the peak. (3)Fig. 3shows the XRD patterns of samples A to E. The pattern of sample A only had a low-density diffraction peak at 2θ...
18、Fig. 3shows the XRD patterns of samples A to E. The pattern of sample A only had a low-density diffraction peak at 2=35, indicating the film microstructure was nanocrystalline with very small grain sizes. Samples B to E each exhibited a hexagonal close packed (hcp) structure, based ...
Jade import ascii pattern files(*.TXT) :通用文本格式,这种格式的文件可由Jade产生,也可读入到Jade中。 在文件名上双击或者单击文件名后鼠标左键单击“Read”,这个文件就被“读入”到主窗口并显示出来。文件的读入方式有两种:一种是读入, 3、另一种是添加。 (1)Read:读入单个文件或同时读入多个选中的文件。

A phase is a crystalline solid with a regular 3-dimensional arrangement of the atoms. The measured diffraction peak positions and intensities are like a fingerprint of a particular crystalline phase. Identification is accomplished by comparison of the measured pattern with the entries in reference da...
The method is performed in the following steps: (i) the diffraction pattern is corrected for background (using a separate diffraction measurement of an empty sample container), Compton scattering, detector dead time, absorption, diffraction geometry and polarization; (ii) the corrected X-ray ...
