What Information Can EXAFS Provide About Nanomaterials?
EXAFS can deliver a wealth of information about nanomaterials, including:
1. Interatomic Distances: EXAFS can determine the distances between the absorbing atom and its neighboring atoms, which is vital for understanding the structural arrangement. 2. Coordination Numbers: It can provide information about the number of nearest neighbor atoms, revealing the local geometry around the absorbing atom. 3. Chemical State: By analyzing the absorption edge energy, EXAFS can give insights into the oxidation state and chemical environment of the element. 4. Disorder and Dynamics: The technique can also provide information on the static and dynamic disorder within the material, which impacts its physical properties.
