What is a storage phosphor?

A storage phosphor is a material that stores a significant part of the energy released on interaction with radiation in long-living traps. In principle, it is similar to an inorganic scintillator, but the trap, which acts as the loss mechanism in a scintillator (Figure 3), functions as the memory bit in a storage phosphor.
