The Zn2p core-level spectra can be fitted by two distinct peaks such as the Zn2p 1/2 and Zn2p 3/2 , corresponding to the 1021.55 eV and 1044.56 eV, respectively, which reveals the strong bonding between Zn atoms and oxygen ions … Web4. Characteristic X-rays. Characteristic x-rays are produced by the primary electron beam displacement of an electron in the valence shell of the specimen. As the electron is displaced, an electron from a higher valence shell must fill its orbit. The result is a small amount of energy loss in the form of an x-ray photon.
