铈掺杂钆铝镓石榴石(Ce:GAGG)是一种相对较新的单晶闪烁体,具有许多有趣的性能,如光产量高,密度高,能量分辨率好,与硅传感器匹配良好的发射峰,低内在能量分辨率。 此外,该材料是非吸湿性和非自辐射性的。 它将广泛应用于PET,PEM,SPECT,CT,X射线和γ射线检测。我司提拉法生长的晶体毛坯直径60mm, 长度约为150mm,可满足客户各种形状和尺寸单晶的加工;同时也可按要求组装一维二维阵列,3m ESR作为隔断。

Ce: GAGG(Gd3Al2Ga3O12) is a new scintillator for single photon emission computed mography, gamma ray and electron detection, it has many excellent properties that make it suitable for gamma spectroscopy and medical imgaing applications. A high photon yield and emission peak around 520 nm makes the material well suited to be readout by silicon photo multiplier detectors, high photon yield is critical for the reduced crystal dimensions of high resolution PET block detectors. Currently GAGG(ce) can be produced at 60mm diameter x 150 mm length by Czochralski.
