 Photostimulated luminescence

Photostimulated luminescence (PSL) is a phenomenon in which certain materials emit light when they are exposed to ultraviolet (UV) or visible light after having previously absorbed energy from ionizing radiation (such as gamma rays or beta particles). This process is commonly used in various applications, particularly in dosimetry (the measurement of radiation exposure) and in geological dating methods, such as optically stimulated luminescence (OSL).
