WebThe resulting electron vacancies are filled by electrons from a higher state, and an x-ray is emitted to balance the energy difference between the two electrons’ states. What is energy dispersive X-ray spectroscopy used for? Energy-dispersive X-ray spectroscopy (EDX) is used to analyze the elemental composition of solid surfaces. When an electron from the inner shell of an atom is excited by the energy of a photon, it moves to a higher energy level. When it returns to the low energy level, the energy which it previously gained by the excitation is emitted as a photon which has a wavelength that is characteristic for the element (there could be … See more X-ray spectroscopy is a general term for several spectroscopic techniques for characterization of materials by using x-ray radiation.
