According to XRD results, the heat treatment of the Fe/ [email protected]/S heat treated at 900 oC leads to the formation of the FeCoS2 phase (66%) along with CoS (33%) phase impurity. The heat...

2019年7月29日 · X-ray powder diffraction (XRD) and Raman characterization. a XRD patterns of the as-prepared cobalt sulfides compared with the standard patterns of CoS 2 (JCPDS 89–1492)...

我们常见的谢乐（Scherrer）公式表达式为：D=Kλ/ (βcosθ) K为常数；λ为X射线波长；β为衍射峰半高宽；θ为衍射角。 在上式中 常数K的取值与β的定义有关，当β为半宽高时，K取0.89；当β为积分宽度时，K取1.0。 但是在实际操作中如何从一张普通的XRD图谱中获得上述的参数来计算晶粒尺寸还存在如下问题：用XRD计算晶粒尺寸必须扣除仪器宽化和应力宽化影响。 如何扣除仪器宽化和应力宽化影响？ 在什么情况下，可以简化这一步骤？ 答：在晶粒尺寸小于100nm时，应力引 …

As ammonium dihydrogen phosphate (ADP) is a popular nonlinear optical crystal, to engineer its linear and nonlinear optical properties, the chalcogenide compound cobalt sulphide (CoS) was doped...

CoS x /C hierarchical hollow nanocages from a metal–organic framework as a positive electrode with enhancing performance for aqueous supercapacitors

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.
