Research Progress of Neutron Scattering Technology in Material Chemistry
In materials characterization,the microstructure,chemical composition and atomic scale information are determined via the interaction of high-energy source with the surface of the sample.However,the accuracy in the detection of light elements limits the application in further characterizing materials.Because neutron has a large penetration depth when interacting with solid matter,it has the capability of investigating the crystal structure,dynamic motion of atoms and magnetic properties,and distinguishing atoms with similar atomic number,isotopes,and light elements.For example,neutron scattering has been applied for studying the atomic structure,hydrogen concentration and ferroelectric properties.Combined with various characterization methods and first-principle theory,the atomic scale information and dynamic properties can be determined.In this article,the principle of neutron scattering were reviewed,as well as the current status of its application in materials chemistry.
