    Ce: YAG  scintillation crystal has distinguished characteristics such as high light output (9000Ph/MeV) and fast decay time(70ns). Also, with the emission peak positioned at 560nm, 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.

    Shanghai North Optics offers the YAG(Ce) single scintillation crystals grown by the Czochralski method. The dimensions could be up to Dia 80mmx200mm. Optional metal coating of Aluminum and silver with a SiO2 protective layer is offered. Ultra-thin YAG(Ce) Screens of 0.05mm free sanding and 0.01mm with substrates are also procurable in North Optics.
