Gadolinium oxysulfide or GOS (Gd2O2S:Pr) is a kind of ceramic with a hexagonal system structure, it has good chemical stability and machinability and is harmless to the environment. GOS doped with rare earth ion has a relatively high light output and extremely low afterglow, which is less than 0.1% at 3 ms. GOS scintillator ceramic has an emission peak spectral range at 470 ~ 900 nm, which is well matched with the spectral sensitivity of silicon photodiodes (Si PD).
Hangzhou Shalom EO offers the GOS scintillator arrays, with linear or two-dimensional designs. Our GOS scintillation arrays are widely used in Computerized Tomography (CT) Scanners, security devices and non-destructive testing systems. If you demand, Shalom EO also GOS scintillation arrays coupled with silicon photodiodes.
