X-ray Fluorescence (XRF)
Published: Oct 15, 2018
If an Element is irradiated by X-Rays it is possible to transfer their energy to the orbital Electron. The electrons move up an 'energy level' in the process. As these energised electrons fall back to their normal state, energy is released in the form of characteristic discrete x-ray Photons which are unique to the element in question. The process is used in analytical techniques where element identification is required.
