<p>Scintillator = A material that exhibits scintillation when excited by ionizing radiation Scintillation = The property of luminescence exhibited by a scintillator when excited by ionizing radiation Delayed Fluorescence = The phenomenon that occurs when the excited state of a scintillator is metastable and the relaxation back down to lower states is delayed Scintillation Detector = An electronic device obtained when a scintillator is coupled to an electronic light sensor</p> Signup and view all the answers

<p>Metastable State = The excited state of a scintillator that is delayed in relaxation back down to lower states Photomultiplier Tube (PMT) = An electronic light sensor that can be coupled to a scintillator in a scintillation detector Phosphorescence = The phenomenon that occurs when the type of transition in a scintillator corresponds to a longer wavelength of the emitted optical photon Luminescent Material = Materials that scintillate when struck by an incoming particle, i.e. re-emit the absorbed energy in the form of light</p> Signup and view all the answers

<p>Ionizing Radiation = The type of radiation that excites a scintillator and causes it to exhibit scintillation Relaxation Time = The time delay required for the relaxation back down from the excited state to lower states in a scintillator Silicon Photomultiplier = An electronic light sensor that can be coupled to a scintillator in a scintillation detector Incoming Particle = The particle that strikes a scintillator and causes it to scintillate</p> Signup and view all the answers

<p>Absorption = The process by which luminescent materials capture the energy of an incoming particle Excited State = The state of a scintillator when it absorbs the energy of an incoming particle Electronic Light Sensor = A device that detects and measures the light emitted by a scintillator Optical Photon = The form in which the absorbed energy is re-emitted by a scintillator in the process of scintillation</p> Signup and view all the answers
