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: conversion, transport and energy transfer to the luminescence center, and luminescence.
The scintillation process is the same as described for organic crystals (above); what differs is the mechanism of energy absorption: energy is first absorbed by the solvent, then passed onto the scintillation solute (the details of the transfer are not clearly understood).
A scintillation counter is an instrument for detecting and measuring ionizing radiation by using the excitation effect of incident radiation on a scintillating ...
The latter then rapidly de-excite by emitting scintillation light (fast component). In case of inorganic scintillators, the activator impurities are typically chosen so that the emitted light is in the visible range or near-UV where photomultipliers are effective. The holes associated with electrons in the conduction band are independent from ...
Twinkling, also called scintillation, is a generic term for variations in apparent brightness, colour, or position of a distant luminous object viewed through a medium. [1] If the object lies outside the Earth's atmosphere , as in the case of stars and planets , the phenomenon is termed astronomical scintillation ; for objects within the ...

Scintillation can refer to: Scintillation (astronomy), atmospheric effects which influence astronomical observations; Interplanetary scintillation, fluctuations of radio waves caused by the solar wind; Scintillation (physics), a flash of light produced in certain materials when they absorb ionizing radiation
This approach can be beneficial for all scintillation applications (for example, medical imaging devices as PET-CT, airport security machines, and free-electron cameras). The best performance of this approach recently showed a 10-fold enhancement in the quantum yield [2] in a micro-CT experiment.
