【求助】The apparent size values (Dhkl) 的意思
|
|||
|
最近在Cryst. Growth Des 上面读到一篇文章，上面讲了利用XRD的The apparent size values (Dhkl)说明各向异性和生长方向性。 The microstructural analysis based on the parameters used in the input control file gave values of the apparent sizes for each individual reflection in order to take into account the eventual anisotropic broadening. The apparent size values (Dhkl) relate the size of the crystal domain with the orientation, and results presented in Table 3 are represents the isotropic crystallite sizes. The biggest apparent size value (D002 = 15.7 nm) corresponds to the crystal direction along the c-axis and that perpendicular to the a-axis. The apparent size in the direction along the ab-axis is D110 = 10.5 nm. The ratio of the apparent size in the direction along the c-axis (D002) and in the direction along the ab-axis and perpendicular to the c-axis (D110) is R (Dhkl) = D002/D110 = 1.5. This ratio is smaller than the standard. 25 But because the R (Dhkl) value is smaller than 2, it can be concluded that the primary sonochemically synthesized particles are of a cylindrical (rodlike) shape. This was also confirmed microscopically. The average apparent size (anisotropic crystallite size) and the standard deviation (anisotropy) were calculated too. Thus, the derived value for the average apparent size is about 10.2 nm, and 3.4 nm for the anisotropy. 这个是如何解释？？求助了解的虫子解决疑惑！！！ 非常感谢！！ |
