2,5-Diphenyloxazole, DPO, PPO, suitable for scintillation, 99.0+%

A scintillator is a material that exhibits scintillation - the property 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).
