X-ray Spectroscopies
X-ray spectroscopies are techniques that use X-rays as a probe to investigate matter. The network offers various instruments that utilize X-ray tubes as sources. Specifically, the instruments can be divided into two categories: X-ray fluorescence and radioluminescence systems. In the case of X-ray fluorescence, the source excites the inner-shell electrons of atoms, and following relaxation processes, the electrons return to their ground state, releasing energy in the form of X-rays. The re-emitted X-rays will have an energy different from that of the incident X-rays, and this energy is characteristic of each element. The X-ray emission spectrum therefore allows for both the identification of the atoms present in the sample and their quantitative analysis. In radioluminescence, the emission of UV-visible light from a sample is studied under X-ray irradiation. This technique is essential for the characterization of scintillator materials, which form the basis of detectors for ionizing radiation. Radioluminescence is often coupled with thermoluminescence measurements. In this case, after irradiating the sample, the emission of thermally stimulated light is studied. This technique is particularly useful for characterizing defects in scintillator materials and is also applied in the dating of ceramic materials.
