Material that absorbs energy from particles, which pass through it and re-emits it as light.
Many physics experiments use a scintillator, a material that emits light (photons) as particles pass through it. The emitted photons are detected by photomultipliers, which transform the light into a measurable electrical signal. Based on the signals features one can identify which particles have passed, for example a solar neutrino or a cosmic ray.
