A scintillator (/ ˈ s ɪ n t ɪ l eɪ t ər / SIN-til-ay-ter) is a material that exhibits scintillation, the property of luminescence, [1] 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 …

In condensed matter physics, scintillation (/ ˈ s ɪ n t ɪ l eɪ ʃ ən / SIN-til-ay-shun) is the physical process where a material, called a scintillator, emits ultraviolet or visible light under excitation from high energy photons (X-rays or gamma rays) or energetic particles (such as electrons, alpha particles, neutrons, or ions).

2023年3月21日 · What is a scintillator? A scintillator is a material that emits light when it interacts with ionizing radiation like X-rays, gamma rays, or charged particles. The word “scintillation” means the flash of light emitted by the material.

2023年5月19日 · 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).

It consists of a scintillator which generates photons in response to incident radiation, a sensitive photodetector (usually a photomultiplier tube (PMT), a charge-coupled device (CCD) camera, or a photodiode), which converts the light to an electrical signal and electronics to process this signal.

What are scintillator materials? 1. Definition and Principle Scintillators are materials that are able to convert high energy radiation such as X or gamma-rays to a near visible or visible light.

For an ideal scintillator and low ionization density Luminescence ∝ Energy dissipated in scintillator or, in differential form The specific density of ionized and excited molecules along the particle track is Assume that a portion of the primary excitation is lost at high ionization density (ionization quenching) and introduce a quenching ...

A scintillator, either a solid or a liquid, is a material which converts the energy lost by the gamma-ray into pulses of light. The scintillation light is detected in turn by a light-sensitive material which usually forms the cathode of a photomultiplier tube.

The properties explained here are light yield, energy non-proportionality, emission wavelength, energy resolution, decay time, effective atomic number and timing resolution. For further understanding, the emission mechanisms of scintillator materials are also introduced.

A scintillator can be any material which emits light when exposed to ionizing radiation; the intensity of the light varies with the energy of the radiation. Flashes of light from a scintillator are detected by a photomultiplier, which converts them into electrical pulses.
