The electromagnetic spectrum extends from below the low frequencies used for modern radio communication to gamma radiation at the short-wavelength (high-frequency) end, thereby covering wavelengths from thousands of kilometers down to a fraction of the size of an atom. The photoelectric effect refers to the emission, or ejection, of electrons from the surface of a sample in response to electromagnetic radiation, or light. The high intensity and tunable energy source at the synchrotron enables. Earlier, Thomas Young (see our article on diffraction here) had demonstrated that a light beam passing through a slit emerges in a pattern of bright and dark fringes. The capability to focus the X-ray beam down to µm and nm, combined with the high flux available at the synchrotron, enables XRF maps with a very high spatial resolution to be acquired on dilute materials; Tuning the energy of the beam facilitates the quantified analysis of detected X-ray intensities and allows XRF measurements to be combined with other techniques e.g. X-ray Fluorescence (XRF) occurs when the inner shell electrons of atoms in the sample get excited by the X-rays and subsequently release X-ray photons when the system relaxes, that is when the electrons transition from the higher energy levels of the atom to the vacant inner shell. The spectrometer measures the difference between the pure spectrum of the light source and the light which passed through the sample, resulting in an absorbance spectrum. All of these facts were brought together in 1859 by Gustav Kirchhoff in his famous law, which states that the emitted power and absorbed power of light at a given wavelength are the same for all bodies at the same temperature. The possibility to study samples with low elemental concentration; The beam tuneability offers a higher degree of energy selectivity. Near-Infrared spectroscopy can be used during the conversion to monitor catalyst efficiency and ensure that the process is limited by equilibrium.
