Co-doping method for modifying the scintillation and optical properties of garnet scintillators

摘要

A method for tuning the performance of a garnet scintillator to meet the specific needs of different applications has been described. Specifically, the scintillator (for example, Gd3Ga3Al2O12 or Gd3Ga2Al3O12 or other rare earth elements / gallium / aluminum / garnet) is co-doped with different ions, so that the scintillation light yield, decay time, rise time, energy resolution, proportionality And / or sensitivity to exposure can be altered. Also, a co-doped garnet scintillator itself, a radiation detector including the co-doped garnet scintillator and related devices, and using this radiation detector, gamma rays, X-rays, cosmic rays, and 1 keV or more A method for detecting particles having the following energy is provided.
