Abstract
Cerium-doped alkaline-earth hafnium oxide scintillator compositions have at least one alkaline earth metal selected from the group consisting of Ba, Sr, Ca, and combinations thereof. The scintillator compositions can be formed into a shape having porosity less than about 0.05 percent for improved transparency. The alkaline earth metal can be partially substituted with divalent and/or trivalent ions other than cerium. Hafnium can be partially substituted with divalent, trivalent, and/or tetravalent ions. The scintillators are characterized by high light output, short decay time, and high radiation stopping power. The scintillators can be used as detector elements in PET systems.
