Superiority
Terbium-doped gadolinium oxysulfide 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 7.34 g/cm3, and shows a not too long decay time, ∼600μs. These properties make forming ceramic scintillators from this phosphor attractive. Ceramic scintillators are profitably employed in X-ray tomography. As early studies show, the ceramic quality depends heavily on the sintering conditions: temperature, pressure, type of activator and co-activator, flux, and heat-treatment. The goal of the present work is to continue and extend the earlier studies of the optical and luminescent properties of Gd2O2S: Tb in order to obtain a better understanding of the physical processes in the ceramics and to find a way of improving their scintillation characteristics.
