GOS ceramic (Gd2O2S) belongs to hexagonal system structure, with no harmful to environment, high chemical stability and machinability. GOS doped with rare earth ion has relatively high light output and extremely low afterglow, saying <0.1% @3ms. The emission peaks range from 470 to 900 nm with the spectral sensitivity of silicon photodiodes, it has been widely used for purposes such as CT scanners, security devices and non-destructive testing.

GOS ceramic (Gd2O2S) belongs to hexagonal system structure, with no harmful to environment, high chemical stability and machinability. GOS doped with rare earth ion has relatively high light output and extremely low afterglow, saying <0.1% @3ms. The emission peaks range from 470 to 900 nm with the spectral sensitivity of silicon photo-diodes, it has been widely used for purposes such as CT scanners, security devices and non-destructive testing.
We are able to fabricate it into linear arrays and 2 dimensional arrays configuration, it can also be coupled with a photo-diode array, which has ultra low dark current, low terminal capacitance and high sensitivity uniformity, this kind of detector modules can be used directly for single high or low energy X ray detection.
