Ce:GAGG Scintillator  Crystal —  A scintillation crystals uesd for high-precision detection The cerium doped multicomponent Gadolinium Aluminum Gallium Garnet crystals, referred as Ce:GAGG with the chemical formula of Ce:Gd 3 Al 2 Ga 3 O 12 , belong to the most important discoveries that offer excellent scintillation properties as well as having entered the scintillator market in the current decade. The effective atomic number is 54.4, and the emission spectrum peak wavelength is 520 nm. Apart from the high light yield, good energy resolution, high effective atomic number, fast scintillation response, chemical stability also ruggedness and capability of large crystal growth are very important properties for Ce:GAGG crystals as well. The linearity of response on the gamma quanta shows Ce:GAGG crystals is a promising candidate for medical imaging techniques, such as X-ray radiography, X-ray computed tomography (CT), positron emission tomography (PET). Single crystal scintillators are f
