Superior X-ray powder phosphor Gd2O2S: Tb for scintillators for x-ray imagi

Superior X-ray powder phosphor Gd2O2S: Tb for scintillators for x-ray imaging

Terbium-doped gadolinium oxysulfide is known as a superior X-ray powder
phosphor with an energy efficiency of emission in the visible spectral region
up to 0.2. Besides Gd2O2S: Tb has a high density, 7.5 g/cm3, and shows a not
too long decay time, ∼600μs. These properties make forming ceramic
scintillators from this powder phosphor attractive. Ceramic scintillators are
profitably employed in X-ray tomography.
