WebOverview. Scintillation is an example of luminescence, whereby light of a characteristic spectrum is emitted following the absorption of radiation.The scintillation process can be summarized in three main stages: (A) conversion, (B) transport and energy transfer to the luminescence center, and (C) luminescence. Luminescence emission occurs after an appropriate material has absorbed energy from a source such as ultraviolet or X-ray radiation, electron beams, chemical reactions, and so on.
