Scintillator

Material which glows when excited by ionizing radiation

A scintillator ( SIN-til-ay-ter) is a material that exhibits scintillation (also termed radioluminescence), a kind of luminescence, when excited by ionizing radiation. Luminescent materials, when struck by an incoming particle, absorb its energy and scintillate (i.e. re-emit the absorbed energy in the form of light).
