Luminescence and scintillation properties of Gd/sub 2/O/sub 2/S:Tb,Ce ceramics

Optical quality Gd
₂
O
₂
S:Tb,Ce ceramics have been sintered by the uniaxial hot pressing method. The heat-treated ceramics offer high transparency in a wide spectral range from 400 to 1000 nm and good scintillation characteristics: high intensity of X-ray stimulated luminescence in the green spectral region and a low level of afterglow
