Ce: GAGG crystal (chemical formula Ce: Gd3Al2Ga3O12, also known as cerium-doped gadolinium aluminum gallium garnet crystal) is a scintillation crystal with excellent comprehensive performance, which is widely used in scientific research and industrial high-energy ray detection. Ce: The effective atomic number of the GAGG crystal is as high as 54.4, and the peak wavelength of the emission spectrum located at 520nm, which matches well with the sensitive wavelength range of the photomultiplier tube (PMT) and silicon photodiode (PD).
Ce: GAGG crystal exhibits stable physical and chemical properties, high thermal conductivity, and resistance to harsh environments. It exhibits excellent scintillating performance, for example, high scintillating efficiency, high light yield, and fast decay time. Ce: GAGG crystals are widely used in photomultiplier tubes, photoelectric counters, scintillation screens, and other devices. And used in high-energy particle detection and other fields, such as beta rays, gamma rays. Because of the excellent scintillation performance of Ce: YAG crystal, it is widely used in CT, scanning electron microscope SEM and other equipment. In particular, the linear response of GAGG crystals to gamma rays indicates that Ce: GAGG crystals are a promising medical imaging technology, such as X-ray photography, X-ray computed tomography (CT), and positron emission tomography (PET). ). Single crystal scintillators are often used in scanning electron microscopy (SEM).
