Scintillation materials and detectors that are used in many applications, such as
medical imaging, security, oil-logging, high energy physics and non-destructive
inspection, are reviewed. The fundamental physics understood today is explained,
and common scintillators and scintillation detectors are introduced. 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. Furthermore, unresolved problems in scintillation
phenomenon are considered, and my recent interpretations are discussed. These
topics include positive hysteresis, the co-doping of non-luminescent ions, the
introduction of an aimed impurity phase, the excitation density effect and the
complementary relationship between scintillators and storage phosphors.
