Description
X-ray fluorescence (XRF) spectroscopy is the emission of characteristic "secondary" X-rays from a material that has been excited by being bombarded with high-energy X-rays, gamma rays or ion beam. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects[1] such as paintings.
