Ce: YAG scintillation crystal has distinguished characteristics such as high light output (8000Ph/MeV) and fast decay time (70ns). Also, with the emission peak positioned at 530nm, YAG(Ce) can be well-matched to CCD sensors. YAG(Ce) scintillators find prominence in various applications like Scanning Electron Microscope (SEM), electronic imaging, beta-particle, X-radiation counters, and imaging. It has outstanding thermal and mechanical characteristics, making it excellent for manufacturing ultra-thin screens of 0.01mm. The fact that YAG(Ce) crystals feature high endurance to high-energy electrons or ions contributes to their wide usage in high energy radiation detection. Besides, Ce: YAG also has the advantage of rich availability in large sizes, all the merits in combination make Ce-doped YAG scintillation crystal a representative inorganic scintillation crystal material. The growth and annealing processes of Ce:YAG crystals determine the practical properties of the crystal.
