XRD衍射图分析,荣涛 2014年4月25日,(d) XRD pattern of the Fe3O4 nanoflakes.,Fig. 1d depicts the XRD pattern of the Fe3O4 nanoflakes. The position and relative intensity of all the diffraction peaks match well with the standard XRD pattern of Fe3O4 (JCPDS No. 88-0866). Based on the Scherrer formula, the average crystallite size of Fe3O4 is calculated to be ca. 15.4 nm by using the FWHM intensity of the (311) peak of Fe3O4.,一张衍射图谱上衍射线的位置仅和原子排列周期性有关 ， 强度则决定于原子种类、数量、相对位置等性质 ， 衍射线的位置和强度就完整地反映了晶体结构的二个特征，从而成为辨别物相的依据。,谢谢指正！,
