Phosphor Gd2O2S: Tb for x-ray imaging and scintillators

Phosphor Gd2O2S: Tb for x-ray imaging and scintillators

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