Phosphor imaging principle
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 … WebVisible phosphor emission colors range from violet/blue to deep red. Some can also absorb and emit energy in the non-visible spectral regions such as ultraviolet and infrared . …
