Photostimulated luminescence (PSL) is the release of stored energy within a phosphor by stimulation with visible light, to produce a luminescent signal. X-rays may induce such an energy storage. A plate based on this mechanism is called a photostimulable phosphor (PSP) plate and is one type of X-ray detector used in projectional radiography. Creating an image requires illuminating the plate twice: the first exposure, to the radiation of interest, "writes" the image, and a … WebApr 17, 2024 · A PSP imaging plate is typically made of a mixture of BaFBr and BaFI, activated with a small quantity of Eu (europium). When X-ray energy is absorbed by the phosphor, electrons associated with the europium atoms are excited and become mobile, and then a fraction of them will get trapped locally in a higher energy state. rayments soham https://ccfiresprinkler.net
